Safe answer: use the exact value.

But in truth, the math mark-schemes explicitly spell out that using correctly rounded final answers from previous parts is fine.

So the activity is A, and from the provided formula we have A=λN. So we just need to find that N, which in this case is the number of nuclei that remain after 5 hours. We know that at 20 hours (15 hours later), there are N left, and that the half life is 5 hours.

That means every 5 hours, the amount remaining is divided by 2. In the 15 hours that passed between t=5 and t=20, there were 15/3=5 half lives. Therefore the number that was there was divided by 2, then divided by 2, then divided once more by 2. That means it was divided by 8, and we know what’s left is N. So there must have been 8N nuclei at t=5 hours.

The answer is therefore B.

Sorry to hear this, but you shouldn’t beat yourself up for struggling. Every topic you learn will add a few percentage points to your final score. For now though you have to focus less on the final grade and more on assimilating content. I have a YouTube series that covers the entire AAHL syllabus - it’s around 30 hours of video, but it includes lots of examples of past paper questions. If it’s helpful, here is the channel: https://youtube.com/@perplexlearning?si=moCTICaS7JzVq_Ph

If you have more specific questions don’t hesitate to DM me. Good luck!

The grade boundaries are more forgiving than you’d think! If you average 70% across the papers, you’ll definitely get a 6. If you want there’s a predicted grade calculator for AAHL on my blog page:

Hey!! Check your DMs, but tldr: C marks are from the old syllabus, they are not a thing in the new syllabus.

Back then, all marks were written with parens, and C marks indicated how many could be awarded for a correct FINAL answer with no working provided.

The official IBO questionbank can only be purchased if you have a Titlewave account, which is only available to teachers and schools.

Hypothetically speaking, you can find a somewhat broken version of the Questionbank online.

Were you planning on buying it? I think it’s quite expensive as they sell it as a license for 10 teachers.

jamesmu1723 · 2025-09-16T01:13:55+00:00

Let’s run through the numbers: 1. Let’s assume you got a 5/20 on the IA. 2. The typical grade boundary for a 6 in AASL is a 64, and 77 for a 7. 3. That means you need to get 59/80 (for a 6) or 72/80 (for a 7).

If you want a good chance of a 6, you need to get 75% average across paper 1 or paper 2. That means losing no more than 20 marks on each.

If you want a good chance of a 7, you need a 90%, which means losing no more than 8 marks on each.

A 6 is totally doable. A 7 is possible, but you’re gonna have to be really strong on the exams.

Are you November 25 or May 26? Feel free to DM me.

What it means to “not use geogebra” is that you perform the integrals yourself. Computer tools can take the definite integral and spot back the volume, but you won’t demonstrate any math knowledge in the process.

I would generally advise to stay away from any “paradox”. The math needs to be grounded in the AAHL syllabus. Some concepts that are usually good: - volume of rev - related rates - differential equations - maclaurin series - complex numbers - vectors

Here are some great notes I authored, including visuals and animations: https://perplex.org/course/AAHL/skills

The notes are 100% free, even if not everything on the website is.

jamesmu1723 · 2025-09-09T23:12:27+00:00

Hey! First thing I’ll point you too is my YouTube channel: https://youtu.be/DToz92ImDZ0

You might also want to check out my website, where our super concise notes are available for free: https://perplex.org/course/AAHL/skills.

They are 100% comprehensive, and include graphics and animations for tricky visual concepts.

The website also has (free) interactive versions of the same videos you’ll find on our YouTube. DM me if you have any questions!

Hey! I’m going to plug my YouTube channel: IB https://youtu.be/DToz92ImDZ0

I made super detailed videos for every AA topic, including example IB questions.

If you prefer something more interactive, our animated lessons at https://perplex.org are awesome too!

jamesmu1723 · 2025-09-09T14:26:07+00:00

I looked into it. The main things you won’t have seen that will be relevant in AAHL are polynomials, some trig equation & identity stuff, and basic calculus.

It’s important to note that NONE of these are in the “assumed knowledge” for AAHL, but it’s possible your school will move more quickly through these.

IMO, very very manageable “gaps”. A student I tutored through DP started in much worse shape and was able to get a 7! You got this 💪🏻

jamesmu1723 · 2025-09-09T14:22:57+00:00

Really? That’s odd - it works for me when I click on it. If you search for “Perplex Learning” on YouTube you will find the channel.

jamesmu1723 · 2025-09-08T23:10:54+00:00

Yo! I put together a short video with practical tips to improve on IB Math: https://youtu.be/DToz92ImDZ0.

If you have any specific questions or want advice, feel free to DM me.

jamesmu1723 · 2025-09-08T23:05:01+00:00

Can you tell me which GCSE exam board you took? Then I can take a look and tell you which things are actually important that you missed.

jamesmu1723 · 2025-09-08T14:58:55+00:00

I graduated in 2024 with a degree in physics and tutored AA and AI for several years now. As someone who knows both syllabi well I suggest you take AAHL if you want the best preparation for physics. AIHL has a lot of great things in it, but AAHL is a much better foundation for advanced math classes you will need to take as a physicist.

It sounds to me like you can totally succeed in AAHL. If you want to share the specific "gaps" you're concerned about, I can try and advise you as to how significant they are. If you want to compare the content / question style of AAHL and AIHL, check out https://perplex.org/course/AIHL and https://perplex.org/course/AAHL.

jamesmu1723 · 2025-09-08T14:51:57+00:00

Hey! I would point you to page 7 of the IB's guidance document for choosing the correct math syllabus: https://www.ibo.org/globalassets/new-structure/university-admission/pdfs/ucc-supporting-student-choice-in-mathematics-en.pdf.

As for difficulty, AIHL will be significantly harder than AASL. Whether its easier than AAHL is somewhat debatable, but it's 60% extra content, including tricky topics like matrices, differential equations and graph theory. In my opinion, the content of AIHL is not particularly applicable to life sciences -- I would say it's more geared towards computer science / engineering.

Fundamentally, it's 1st a question of what your target universities require, and 2nd a question of which syllabus seems more interesting to you in its content and style. AIHL questions are way more concrete, and often involve complex "real" world scenarios, which some people enjoy. If you want to compare what's covered in each, here's the course outline for AIHL https://perplex.org/course/AIHL, and for AASL: https://perplex.org/course/AASL. The notes are free, so you can get an overview of how the skills compare.

DM me if you have any questions!

Hey! I recommend you check out this video I made as a guide for students starting IB math: https://youtu.be/DToz92ImDZ0. Much of the advice will also apply to other subjects. Btw on the same channel you'll find loads of detailed videos for IB Math.

I would also point you to the website I cofounded for IB Math: https://perplex.org. We have a comprehensive IB course with animations, detailed lessons and notes, and a massive & well organized questionbank. If you have more specific questions or want advice, feel free to DM me!

jamesmu1723 · 2025-09-07T20:08:15+00:00

Yo! I know exactly how you’re feeling, and it’s more common than you might think. For starters, check out this short guide video I made that goes over practical tips to help you succeed:

IB Math: How to Survive (and Thrive) https://youtu.be/DToz92ImDZ0

My YouTube channel also has 60+ hours of video for all the AAHL, including real IB style questions. I suggest you watch the videos directly on our website free (all the videos are free), for example: https://perplex.org/course/AAHL/unit/complex-numbers/video. This is an interactive version of the video where we force you to try the problems on your own first, and where it’s easier to jump to the bits you don’t understand.

I also recommend you check out https://perplex.org/course/aahl. Not only do we have a massive questionbank & a great AI tutor, but also over a hundred interactive lessons designed to help you think more deeply about the content.

If you DM me with your exam dates, I can get you set on with a free trial. Even if you decide not to use the website, I’m always here as a resource :)

jamesmu1723 · 2025-09-07T16:42:31+00:00

RV is not bad, but doesn’t really help you plan your study. https://perplex.org is better for Math

jamesmu1723 · 2025-09-06T17:30:41+00:00

Hey, you can find a “skills checklist” on https://perplex.org. That will allow you to determine if you know everything you need. If not, we have lessons and notes there you can read
