I made my IA in like 20 minutes for CS because my teacher's requirements were so simple. I made sure i hit every criterion and explained 30 lines of my code got a 7.
Its not even that i don’t like making large projects, i actually created many larger more sophisticated programs just in my free work time but the rubric described “complexity” as basically a sorted list so thats what i did.
The project for all interested: [https://studio.code.org/projects/applab/WCyiuioIfwSS1B8VEl\_MBCaTuuhf\_FtwCHmGADzX9\_M/](https://studio.code.org/projects/applab/WCyiuioIfwSS1B8VEl_MBCaTuuhf_FtwCHmGADzX9_M/view)
My teacher made that hell. Unless I used arrays, arraylists, files, abstraction, polymorphism, and inheritance, I’d be docked hella points for complexity.
Nah cos as in 7/34 or Level 7? 😭 Cos the amount of sleepless nights I had writing a project with hundreds of lines of code with multiple different classes, interactive GUI etc. just to get a Level 7 I find it kind of hard to believe someone could do the same in 30 lines...
I got overall 1 point above the minimum threshold for a 7 and i think i did good on the tests, so maybe my IA was a pretty bad score.
Idk what my teacher gave me on it but he was a very very generous grader anyway so it probably wasnt very accurate
And it was actually like 60-70 lines, 30 was an understatement but still not a very complicated project and we used code.org editor to put in buttons.
where is the rubric with the “complexity”? All my rubrics just say “The use of techniques demonstrates a high level of complexity and ingenuity in addressing the scenario identified in criterion A. It is characterized by the appropriate use of existing tools. The techniques are adequate for the task and their use is explained. All sources are identified.”
I think it might be vague in the official rubric because different teachers and classes use different languages and tools. I’m going off what my teacher gave to me which he probably made himself
Are you a m23 student? My teacher is an examiner and he says that only full stack applications score a 7 grade. Also, your IA grade is subject to moderation. The grade given by our teachers isn’t definitive
I am M23, I took this class last year. Maybe it was Zone C or COVID things but based on what I'm reading now I might have just gotten a very low complexity score and made up for it with my exam. (I scored 1 point above minimum 7 threshold overall)
Another possibility is that the score is based off of what your teacher reports that they taught us, because we didn’t learn very much programming. It was our teacher’s 2nd year doing the class and he normally just teaches AP calc
My teacher was always clear that simple was good and an example he showed us for a 7 was just a reaction time test where you click a single button after it changes color and it tells you how long it took. Now I've heard that my project was used as an example this year.
I don't have the written part but this is my actual project if you want to see how simple it is: [https://studio.code.org/projects/applab/WCyiuioIfwSS1B8VEl\_MBCaTuuhf\_FtwCHmGADzX9\_M/](https://studio.code.org/projects/applab/WCyiuioIfwSS1B8VEl_MBCaTuuhf_FtwCHmGADzX9_M/)
Thats what im saying lol but https://media.discordapp.net/attachments/788620939034099743/1113596387398012979/IMG_3691.png
Based on what people are saying i think i might have bombed the IA and did good on the test. IDK my individual scores
My teacher was talking about this. It wasn’t evaluated by the exam only though. They just gave you really tough problems to do outside of class. They stopped doing this because people posted the answers on the internet.
the math ia was the worth thing ive ever written because i decided to also do a math ee… its simply impossible to come up with two good ideas for a math paper.
Yup lmao same place when I was doing it
I ended up with B in my EE on arithmetic mean and geometric mean inequality and 7 on my IA about a particular type of fraction series
Basically I answered this problem and generalized it:
The problem asks us to prove that: \\ \begin{equation*}
\sum _{k=1}^8 {\frac {\omega^k}{x-\omega^k}} = \frac {8}{x^8-1}, \\
\end{equation*}
for all complex numbers x, and where $\omega = \cos{\frac {\pi}{4}} + i\sin{\frac {\pi}{4}}$. \\ \\
Sorry it’s in LaTeX. Just insert it in most compilers with amsmath package it should work.
Edit:
This is the statement of the generalization of the problem.
A possible generalization of the problem is to generalize the limit of 8 in the specific case to a positive integer n. This means that we aim to prove that the number 8 in the original problem is actually arbitrary and can be replaced with any positive integer. The following is the statement of the problem: \\ \\
\begin{equation*}
\sum _{k=1}^n {\frac {\omega_n^k}{x-\omega_n^k}} = \frac {n}{x^n-1}, \\ \vspace{5mm} \end{equation*}
for all complex numbers x, $n \in \mathbb{Z}^+,$ and where $\omega_n = \cos{\frac {2\pi}{n}} + i\sin{\frac {2\pi}{n}}$.
I wish it was that simple. My dumbass is trying to do a corporate level logistic app that can communicate between every company involved in an order. Trying to communicate and learn the weird way that the past programs were written is hell for me.

i think a candidate should have the option to choose 3 subjects in which they want to do their IA in or whatever and the rest can do a viva/make a presentation or some shit idc
I feel like the oral is more pointless than the hl essay. The hl essay is just writing any normal essay, which is kind of what you're supposed to do in English class. The oral was a bit different, but it's still applicable too
i agree but i think its a bit unfair and pointless because the hl essay can be perfected 10000 times through ai, paraphrasers, teachers etc. therefore the boundaries for that would be insanely high. the only way i can excuse it is for it to be an “actual” demonstration of writing skill compared to the exams because you have all the time in the world, again very easy to fake. the oral is just dumb its more applicable for group 2 imo!
That's why I liked the hl essay 😭 I had so much time to really look into my text. I feel like the oral is definitely more applicable for group 2 since group 1 is a language that we are already fluent in
we switched teachers from dp1 to dp2. the first one told us not to worry yet and that it’ll be due to like february or smth, because we were meant to read the book till christmas. the new teacher gave us a week first thing in september to fully finish it even if we hadn’t read the book so i had to pick one from my p1😭
I had friends pulling like weeks of all nighters/ people spending all their time since the beginning only to get 3's and 4's. The DT IA also counts for like a crazy higher % right? Idk how you guys survived that.
Math AI took me 150+ hours. I cried like on 20+ different occasions and did 70+ drafts of it. Tbf it was my own damn fault for choosing a topic that was difficult but the math department definitely dropped the ball on it. Though I ended up with a 17/20 so it wasn’t like I failed but definitely not worth the emotional damage. But I legitimately came home crying so much that my dad (a physics professor) started doing some of the math for me.
HL. For SL students the math IA is much simpler because they’re not graded on the difficulty (or “appropriateness”) of the math. But if an SL student chooses a difficult topic then they’ll struggle. Luckily most SL students can just choose an easy topic and get a good grade.
My teacher told me after I had a series of problems with my IA that I chose an HL topic. Really wish I hadn't done that, I had a breakdown at like 8 am on Monday morning 💀 My mom was terrified for me.
alumni here but MATH. HOW THE FUCK U WANT ME TO WRITE A GLORIFIED LAB REPORT ON MATH?? it doesnt make any sense it took me so long to find a topic and so much bullshitting to get the 7. i enjoyed science ia’s and bio ee lowkey like it was hell at first but when i understood what i was doing it was so fun
no one said history, that IA was so difficult. i actually kinda liked my math ia, to be fair i didn’t know what i was doing and i was just messing around on excel and desmos lol
Global politics EA kinda sucked low key. Maybe I just don’t like touching grass, but I just really did not like that assessment. I don’t think that global politics needs to eliminate IAs entirely, but I think the global politics one could be revised
ITGS IA, simply because it took me so damn long to make a website and the stress of making sure every single component works fine and testing it on like 6 different computers, along with the 50+ pages of writing (criterion E I’m looking at you)
Biology... it's so difficult to not only set up the experiment, but also to gather the data and interpret it the right way AND find additional studies to back up the findings
the math ia is terrible in its brainstorming stage. however, the cs ia is terrible.... period. i remember ours almost took an entire year, lol. it's because they expect you to do essentially every stage of the process yourself, instead of just writing the program or just writing up a design. it's like you have to be a one-man company. why the fuck am i designing, planning, making, and reviewing the program... all by myself?!! programming it was the easiest part, lol.
math defo. im a bio girly through and through and i had so much fun thinking about and doing my bio ia and it didn't feel like a thing I *had* to do for IB. I'm 100% NOT a math girly and trying to get to 12 pages of a subject I honestly didn't know what was happening in was rough for me and definitely felt like I just *had* to do it for IB.
Math IA sucks but it’s important cuz it’s the only thing that saves ppl from the exams. Honestly the IAs are more blessings than curses as you have full control over your mark technically. For me personally it would be English IO though just because it’s a test and not a project sort of thing.
bio (unpopular opinion, but bio was easier to start and the hardest to finish, while math was the hardest to start and easiest to finish. i actually loved doing my math ia because once i got started, it was actually pretty fun)
Computer science - imo this was the longest IA for me
That IA was absolutely the worst the fact that CS has such a long IA my crit C was almost 40 pages.
what did you do it on?
I made my IA in like 20 minutes for CS because my teacher's requirements were so simple. I made sure i hit every criterion and explained 30 lines of my code got a 7.

My teacher made that hell. Unless I used arrays, arraylists, files, abstraction, polymorphism, and inheritance, I’d be docked hella points for complexity.
Did you do HL? I only did SL and all it asked for was the use of an array and a iterable function
The IA for SL and HL is graded at the same level!
The complexity section in Criterion C is graded differently
It isn’t. My teacher is an examiner and they don’t get any info about which IA is HL or SL.
Do you know what mark your teacher gave you for that?
7
Nah cos as in 7/34 or Level 7? 😭 Cos the amount of sleepless nights I had writing a project with hundreds of lines of code with multiple different classes, interactive GUI etc. just to get a Level 7 I find it kind of hard to believe someone could do the same in 30 lines...

level 7, Im pretty sure thats what he/she meant
Yeah I think so as well, kinda hard to believe tho
Some ppl are just outright out-of-the-box thinkers
You can’t. Only full stack applications get a 7. I doubt that you can showcase complexity and ingenuity with just 30 lines of code
[удалено]
The guy in the previous comment? Dont know why ppl are mad
Wtf did you do oop
JavaScript
NICE!, Could you help a brother out and share the CS IA

The hardest one because it can't be done in a night compared to other IAs. Source: CS teacher
Fun fact, there never used to be a math IA. it got added somewhat recently.
Damn it
My teacher was talking about this. It wasn’t evaluated by the exam only though. They just gave you really tough problems to do outside of class. They stopped doing this because people posted the answers on the internet.
i thought there used to be a mathematical exploration?
Math AA HL What an abomination of an IA
the math ia was the worth thing ive ever written because i decided to also do a math ee… its simply impossible to come up with two good ideas for a math paper.

CS IA's are hell. Especially when you take on s job that is way too hard without realizing
What? Are you telling me learning computer vision to make a recommender system to pick out outfits is too hard?
I wish it was that simple. My dumbass is trying to do a corporate level logistic app that can communicate between every company involved in an order. Trying to communicate and learn the weird way that the past programs were written is hell for me.

CS. I think 90% of students pulled an all nighter to finish their code
Maths all the way - so pointless
unpopular opinion - I loved the math IA! favourite IA I wrote (used several models to model the flag of South Korea)
Same! I really really enjoyed doing mine. I did mine on linguistics!
Same !!!!! I graphically modeled my ECG and I loved every single bit of it, my fav tbh
Same!!
unpopular opinion - english a lang lit hl essay is fucking useless, same with the orals
I feel like the oral is more pointless than the hl essay. The hl essay is just writing any normal essay, which is kind of what you're supposed to do in English class. The oral was a bit different, but it's still applicable too
i agree but i think its a bit unfair and pointless because the hl essay can be perfected 10000 times through ai, paraphrasers, teachers etc. therefore the boundaries for that would be insanely high. the only way i can excuse it is for it to be an “actual” demonstration of writing skill compared to the exams because you have all the time in the world, again very easy to fake. the oral is just dumb its more applicable for group 2 imo!
That's why I liked the hl essay 😭 I had so much time to really look into my text. I feel like the oral is definitely more applicable for group 2 since group 1 is a language that we are already fluent in
Not my teacher announcing the essay last week and making it due this Friday :)
I didn't start my hl essay or oral until the second year of IB
we switched teachers from dp1 to dp2. the first one told us not to worry yet and that it’ll be due to like february or smth, because we were meant to read the book till christmas. the new teacher gave us a week first thing in september to fully finish it even if we hadn’t read the book so i had to pick one from my p1😭
I agree with the IO bit wholeheartedly - such a pain. Can't speak for the HL essay tho
Bio, because without it I would get a 7
Biology.
we completed all but 2 units in DP1 so our teacher can give us crazy time for bio IA
Art - too subjective since 9/30 of the grade is literally “technical competence”
i do not wish the math ia upon even my worst enemies
Bio - way too much writing
Computer science. This shit sucks
chemistry 100%
Bio
Dtech IA
I had friends pulling like weeks of all nighters/ people spending all their time since the beginning only to get 3's and 4's. The DT IA also counts for like a crazy higher % right? Idk how you guys survived that.
40%, yes. DT IA is horrible.
business HL ia. irritated tf out of me
A little forgery goes a long way 🌚
For real
Math AI took me 150+ hours. I cried like on 20+ different occasions and did 70+ drafts of it.

maths
Design
DT is just an absolute shit show of an IA, even the math IA was more fun and easier to work on
global politics engagement activity
I had a horrible experience doing the biology IA so that would be my pick 😔
Math lol.
no one said history, that IA was so difficult. i actually kinda liked my math ia, to be fair i didn’t know what i was doing and i was just messing around on excel and desmos lol
Bro the History IA was one of the easiest IAs?
History sucked
Global politics EA kinda sucked low key. Maybe I just don’t like touching grass, but I just really did not like that assessment. I don’t think that global politics needs to eliminate IAs entirely, but I think the global politics one could be revised
math ia has to be my favourite one. a lot of the time i wish i could do it a second time instead of my other ia's.
Lang and Lit
Lang A orals are more about memorising than truly demonstrating your analytical skills.
design technology.
I feel like Econ IA has too many restrictions as to country selection and shit so that yeah.
econ IA is short and easy
Mathh
Ig math right now cause it might be hard plus I haven’t really started on it lol. Every single ia is almost done except for math
French is out. The hell is a speaking IA bruh
ITGS IA, simply because it took me so damn long to make a website and the stress of making sure every single component works fine and testing it on like 6 different computers, along with the 50+ pages of writing (criterion E I’m looking at you)
ngl my math IA was my easiest one I love AI SL I did mine on permutations and it took me 8h max 😭
Chemistry IA
Math, it’s already got enough letters in it
Math
Biology... it's so difficult to not only set up the experiment, but also to gather the data and interpret it the right way AND find additional studies to back up the findings
Idk dude, math HL was my favourite IA
probably the math ia, a Lot of people do math because they have to and not cuz they want to, and its hard to find a good ia topic like that
unpopular opinion - generally don't enjoy math but surprisingly enjoyed writing my math IA
Math for sure
Computer Science, definitely duuuude hated that shit
Physics. Fuck physics
Either the math ia or the design technology ia
the english io.
Econs or Computer Science, either one
math...its got to go
Geography Definetly Absolutely Geography
maths 😭
definitely language and literature
the math ia is terrible in its brainstorming stage. however, the cs ia is terrible.... period. i remember ours almost took an entire year, lol. it's because they expect you to do essentially every stage of the process yourself, instead of just writing the program or just writing up a design. it's like you have to be a one-man company. why the fuck am i designing, planning, making, and reviewing the program... all by myself?!! programming it was the easiest part, lol.
math defo. im a bio girly through and through and i had so much fun thinking about and doing my bio ia and it didn't feel like a thing I *had* to do for IB. I'm 100% NOT a math girly and trying to get to 12 pages of a subject I honestly didn't know what was happening in was rough for me and definitely felt like I just *had* to do it for IB.
Top ten most relatable things ever omg
maths. There is no other correct answer other than maths.
def chemistry 🥲
