I have my chem hl test in a bit more than 3 weeks.

I've already tried all the new syllabus past papers (2025 may to 2026 may) and am looking for some worthwhile old syllabus papers to practice before my exam.

What were the hardest past paper in Chem HL?

It makes IA's horrendously hard to write for no good reason as far as I see it. It excludes valuable documents in analysis and limits a lot of what can be said and supported. Im not educated enough to understand why this is the case, can somebody please explain why the IB made it like this?

I am about a month and a half into DP1 and time management is already getting to me. I just wanted to ask anyone how they are possibl managing their time. I get I take hard subjects but it feels like its impossible to even get sleep anymore if I want to get a good grades (also yes I am aiming high on the IB so... idk my work has to be good quality)

Thanks guys for any advice as always!

(also ive tried searching this up and none of the advice has been any help thats why I'm asking here)

Hey everyone

Here is the topic I currently plan on doing for my Math AA HL IA (not the exact RQ, just the general idea): It's pretty much me recording myself running and tracking the movement of one ankle over several strides, then using piecewise, trigonometric and parametric functions to model its trajectory.

I would use differentiation to calculate velocity and acceleration, integration to calculate the distance my ankle travels, and then incorporate physics and some reasonable assumptions to investigate the optimal running cadence (steps per minute) that theoretically requires the least energy at a constant speed. I'm still figuring out the exact physics model for the optimization so ideas for that would also be nice.

Any thoughts on this topic? Is it feasible for a high-scoring Math AA HL IA? Thanks!

I am basically doing statistics for my math AA IA but all the math I did was just plugging in the data into Desmos/Excell, calculating averages, and doing small substractions for my data.

I have one main data table and a reference data table (composed of an average /12 but plan on increasing that number).

Thing is - the main data table has an r^2=0.42 when it’s a quadratic equation and r^2=0.68 when a quarTIC equation.

Needless to say, its total trash. And Idk if I should start over but this will definitely score me a max 3 for personal engagement Ig…

However, from what I heard, as long as I can properly reflect upon this and use good amount of manual mathematic calculation then it should be somewhat alright.

But I can’t think of any decent math to put into this sooo any suggestions?

RQ is about how can the independent (age) value be used to predict the dependent (time duration in UFC fights) value

These are some random questions I have. If anyone could help, I'd appreciate it.

For context, I'm M27 and using title n.4 (To what extent do you agree with the claim that ‘any coincidence is worth noticing; you can throw it away later if it is only a coincidence’ (Agatha Christie). Answer with reference to mathematics and one other area of knowledge.)

1. Do I have to necessarily evaluate two perspectives (I agree/I disagree), or can I use

   a

2. third one like: "partially agree"?

3. How much do I have to involve a real life situation? Do I just discuss it a bit in the intro and then never mention it again? Do I tie back to it afterwards?

4. Should I focus on one discipline inside an area of knowledge or can I use multiple? Is there a "sweet spot"?

5. How do I use as evidence examples that are in both areas of knowledge? Can I do it however I want since the essay has no structure?

If I have any other questions while writing, I'll edit the post or comment.

Thank you in advance to anyone who can help me!!

hey guys, anyone with revision dojo cheat sheets please dm me im in dire need of them😪

Feel like I got scammed when I bought bio SL for revision village, there's very few paper 2 questions . I found save my exams but that's also paid. any free resources?

RV History questionbank is decent but I'll probably need more since I've done a lot of them

Thanks!

Would anyone who got an A on their IB Psychology EE be willing to help review mine? My internal deadline is in 2 days, and I feel like mine is very shallow. Thanks!

Hey were can I find complete IB guide from ib academy ? Does anyone know ? Or has an alternative for bio hl and maths aa hl please, thankss

I am a dumbass student, my grade is currently a 4/7 for maths aa HL, like deadass I don't know how some kids ace this subject, I have been reading the slides and doing questions but I am like hardstuck 4, how do you 7 kids study and what resources do you use because my teacher seems to use questions that are completely different and weird in comparison to the Christos Nikolaidis questions that I've been doing, I deadass need some real effective methods, because the 7 students that I ask in my class are apparently prodigies that don't study so idk atp. Any help is appreciated thankss

hi guys. I absolutely suck at p2 and writing in general. I have an English p2 tomorrow and I’m done for. For future reference l, how can I improve? What did you guys do to be successful? I always piss myself off when I see the abhorrent things I write. My writing is just useless slop, where the sentences are unnecessarily long or not structured well enough. I can never seem to reach the level I want. Writing just reminds me how behind and incompetent I am.

I know literally everyone that does IB hates how arbitrary TOK is, but I think it's a great way to get easy marks, so here's some tips from someone with a modded 9/10 on their TOK essay!

I wrote on the M26 question [4]: "In the acquisition of knowledge, can we only understand something to the extent that we understand its context?"

(1) Picking a question

Q: Are there "easier" or "harder" questions? Is there any question you should or shouldn't pick?

A: This is a bit of a myth (from my TOK Coordinator who's done it for 10+ years), but there are technically "harder" questions. Obviously, don't pick the questions that involve AOK that you're not familiar with, and make sure you are comfortable with using examples. Our coordinator also mentioned that if the question is '"XYZ claim", do you agree?', then unless you are confident in your writing skills, it is quite dangerous to tackle it.

(2) Coming Up with Examples

DO NOT USE AI. I know that it is tempting, but don't use AI for examples, it genuinely gives you the most overused examples and it's horrid because it is your job to put together a cohesive essay.

Anything can be an example, and if you pick AOK that you are interested in, you can really come up with good ideas. It might seem random at first, but for instance, I used a school of literary analysis in my essay. It is important to know the theories in depth or at least have a lot to say about it.

Mentioning theory, in my opinion, was how I got a high score. Show genuine interest and I feel like it makes a difference, one of my friends wrote on Hatsune Miku I'm pretty sure.

(3) Composing a Good Response

Make sure that you structure the essay in a way that there is active back and forth -- this is why it is so important to to not use AI. Try give it your all and write an argumentative essay, this is the format I used, very simple:

Introduction - include thesis i.e. answer to question

AOK 1: FOR your thesis

AOK 1: AGAINST your thesis (rebut this)

and then rinse and repeat for AOK 2. It's not a long essay, so just make sure that everything is tightly packed.

Good luck!

I am writing my EE in English and I am thinking of using 2-3 short stories and analyse how author uses 1 literary device in them.

how does {Author} uses Imagery to potray the theme of Humanity in his {name of short stories}

This is not my real RQ but kinda what mine will look like. However, my question is whether using only 1 literary device enough or is it to simple?

I am analyzing how the authors uses it and what meaning and effect it creates, but not sure if this is good for Exttended essay or too simple?

I had to match thousands of ward codes between the 2021 and 2025 local election datasets to find my 726 matched wards. I could not do this manually as I am doing elections between two palces between 2021 and 2025 the names of the places have disappeared and I can not physically do it so I asked AI to find the places that matched for me in 2021 and 2025.

My actual math is all calculated and explained step-by-step by me. But I'm wondering: is this allowed? is this aginst the academic integrity rules?

Hello, I like to know what would be a good grade for this uni, as I will be applying with pg for the 2027 September to GLA snd GS programs.
My predidced is a 36, 2 additional point, all 6 and a 4 for Spanish ab.

Do universities actually look at this and is it a criteria in whether they accept you to their course are does it not matter that much? Because I take: Chem HL, Bio HL, French A HL, Math AA SL, English A LL SL, and Econ SL, and am hesitating between doing my EE in either Bio or French A. Biology i have a slight research direction but ik that it’s going to take an incredible amount of time and dedication to pull off and hit top marks, while french seems easier and if i have to be honest, more enjoyable for me as i’m thinking I could write a category 3 one about dialogue in a movie a love. But then, I was told I should do it in the subject I want to study in (which is bio) as uni’s will accept that a lot more… So I am quite conflicted… What do you guys think?

Hey guys! Does anyone know where I can get ib past papers from 1999 to 2009? ib.docs only has 2010 onwards, and I'm wondering where I can find the papers before 2010. Thank you.

It's 135 usd per month now, has anyone else noticed this?

...

asking for a friend..

or is there any similar/good alternative for it?

(also why tf did this get flagged for academic dishonesty or whatever)

im planning on submitting early round and then submitting my final grades afterwards if possible, like im sure i can up my chinese, econ and maths to 7 so its like (40/45) but im just really scared i cant get into the courses n its stressing me alot..

Hey guys my bio IA was similar (same question but the range of IV was different) to another student that I came across on clasify months after submitting my IA, and i found out some of the wording is the same. It was no intentional, some of the sentences included generic phrasing such as "ethanol is toxic and may cause irritation to skin and eyes' and 'enables for maximum level of absorption' and a fewer other sentences et.c With this being said I am extremly scared of cactus 64 picking this up. My teacher isn't letting me make changes so I am so scared.

Are there any moderators or people who work at IB who have any experience to tell me if I could get caught for accidental plagarism or if cactus 64 works differently?? I am scared.

Hi I'm DP1 student and our teacher let us to choose our general interest(s) topic(s) for writing EE.

My 1st choice is Bio, 2nd is math, 3rd is English B.

Here are some topics

Biology: Enzyme activity, plant responses to environmental stress, seed germination, cellular respiration.

Mathematics: Optimization, geometry, sequences and series, graph theory, number theory, and the mathematics of music.

English B: Language in advertising, identity and belonging in literature, persuasive language in environmental campaigns.

I'm not sure whether I chose the good ones
My aim is to get a A or B

pls tell me if its ok.

Yipppppppeeeeeee

I'm freeeeeeeeee
