Hi all! I'm currently using the "Mathematics for International Student" (Haese & Harris Publications) as my main maths textbook and I was wondering if that would be enough for me to achieve good marks for Maths HL. There's another Maths book by IBID press but I'm not sure if its worth for me to get it Or should I just do questions from past papers? What ar ur thoughts?

Author's Note This is the third draft of a concise guide I'm working on in regards to the new mathematical exploration IA; this started as an HL guide but has now been generalized to include the SL curriculum as well. Please do let me know if there are any improvements you can suggest, or any questions you have after reading through this. I plan to keep this updated and add to it as I work though my own IA. Thanks for taking the time to read through!

I'd love it if you could share some tips and tricks for papers 1, 2 and 3. I'm at a stage where maths is kinda worrying me. I'm on my holiday break right now, but when I get back to school, my teacher's getting us to do all the papers to 'give us a chance to get higher predicted grades' for our uni applications. He's also said that if we don't manage to get at least a 4/5 overall, he'll enter us for the standard level maths paper which I really, really, really don't want and can't afford at all. As the dreaded may exams are inching closer (four months to go!), the worry's slowly consuming me. So, I thought about perhaps starting a thread where we could somehow gather…

I have been reading into the IB programme and the subjects that my school has assigned to me for the next two years, and the one that worries me mostly is Maths HL. I am a good maths student but whilst speaking to other people and reading this forum I have gotten the impression that the subject is quite difficult and challenging, but also I have some questions. 1) Discreet mathematics; series and differential equations; sets, relations and groups; statistics and probability. Shall my Maths HL class encompass all of those or only one or a few? Are they all needed to pass the IB Maths HL exam? 2) Considering the difficulty of the subject, should I make an effort during this…

Hi guys, I'm about to submit my IA idea for math and I just want a few pieces of advice choosing one. Currently, I'm very much interested in cryptography and machine learning which are the topics that I want to do my Math IA on, are these viable ideas? Earlier when I talked to my teacher, he said that writing about the Global Positioning System (GPS) would be a great idea, but I'd much prefer the other two topics. What should I do to ensure that I get a high grade while doing something that I actually enjoy?

Finally found an IA Topic after weeks of researching. Planned to do something on queuing theory. Read through it and understood that it's mainly calculation with arrival rate, time to wait before reaching the end of queue etc. (Correct me if I'm wrong). I'm just not sure how an IA is supposed to look like when applying queue theory. Choose a situation and start investigating the values? Is it just that? Is there suppose to be more to it than just calculations. Just felt quite sceptical and had to ask. Anyone out there who has done queuing theory before is kind enough to share with me your experience or even example IAs? And also any other tips to find…

Hello Everyone, I am a graduate of the IB on MAY 2018, and I had always been a student who was pretty good at math. I did MYP, and slid through it with 7s all along in Math. I then was told by my teacher that Math HL would be suitable for me and that it would be a good challenge. At that time I thought, yeahh but I will just go in and prove that its easy. My first Sequence and series test, I got a 3, and was in terrible shock, I had never seen below a 7 in years in Math, and the MATH HL IB CLASS had a first test given to me that was a 3. I continued and it seemed like after I had a talk with the IB DP coordinator who feared that maybe HL Maths was the wrong choice fo…

Hi everyone, I was wondering if I could get your opinion on whether this topic is appropriate for a Math Exploration in HL. I am planning on analyzing Poker Odds, mainly by focusing on Pot and Card Odds. I will certainly be using conditional probability, Bayes Theorem, Factorials, Permutations, etc. I will basically give an invented scenario and, from there, I will find the probabilities of having a certain hand and of winning based on the opponent calling or betting. I will also use probability to determine if the odds of the hand are profitable to continue playing. So, what do you guys think? Do you think this is a good topic and that the math used is appropriate for H…

I chose to demistify the number e for my math IA. What I have so far is how we came up with e throught solving continuous compound and calculus. I'm also planning on putting in some explanations why e exists in some important formulas. I was wondering if there is anything else I should add? So far I have only explained how we created e, I haven't done much on going calculations of my own. Regarding this topic, is there anything I can calculate? What other reflection, analysis should I do on this project? Thank you.

I graduated IB in 2018 and studied Math HL with discrete math as my option. I also wrote my EE in mathematics / physics and received an A. I'm currently studying programming / computer science and game design. I replied to a post a few years ago about writing Math IAs where I gave some advice and talked about my paper and a lot of people requested copies of my IA for reference. I've heard that with the covid situation and online learning a lot of people are facing some challenges with their research and are doing explorations based on previous students' work etc. With that in mind I thought I would make a post offering to share some of my resources and advice based o…

Heya, so basically for my math IA I decided to make my own life hard and choose a topic like 'celestial navigation'. More specifically, I'm doing my paper on smthing along the lines of 'how to find your geographic location using celestial navigation'. Soo, I was wondering if anyone could possibly help me out? I've found some resources but I'm still very confused on how to use them and stuff like that, so if anyone would be willing to lend me a hand, pls let me know as soon as you can, bc ya boi is running out of time due to my own procrastination.

Hello everyone! Now I am 10 grade student at IB school and im on that period of time when we need to choose the DP subjects. I wanted to listen to your advices on how to choose a math course correctly. I am not sure what I want to take as a major. but I am really interested in Economics and Engineering stuff. I am planning to take Economics as HL and probably Physics as HL. Also, I am a really math enjoyer but the problem is I don't have high marks in it, I ended up 9th grade with 5/7. I do really understand every topic in the class but on the summatives we get some 1 course stuff lmao. so, pls help me, I am open to every idea

I'm M24, working on my maths IA now, with no help from a teacher. Our maths teacher tells us to chatGPT everything related to the IAs (despite the fact that they are literally incorrect about IB regulations), and then when we come up to her for confirmation of our topics, she immediately says: "you lost me." This is how lots of independent research lead me to the following possible questions for my IA: 1. How can SAT (separating axis theorem) be extended to handle dynamic objects with changing shapes and orientations in realtime? 2. How can SAT (separating axis theorem) be extended to handle dynamic objects with changing shapes and concave and convexity? 3…

Hey, Currently I am thinking of doing Dijkstra Algorithm for my IA (calculate the shortest distance), but it doesn't seem enough, what should I do?
Last reply by eylul, 
I am currently thinking about Math IA on the topic of graph theory, but I don't know what to choose from there. I would like to do Dijkstra's algorithm and would like to know whether it would be complex enough for HL. I am thinking about the question of geographical traversal and finding the shortest path from London to Moscow using roads and cruises to cross the sea.

I decided to take math HL for next year (grade 11). But everyone keeps scaring me about it. All my future iB friends have all taken English HL. They all keep telling me about how math HL is like suicide. Like how these kids who took regular math had like 98%, they came into math HL and ended up with 60%. I don't want my mark to be 60%! To give some of my background, I am NOT a genius, but I do enjoy math a lot. For those of you that know the Cayley math conest, I got 114 points, putting me in the top 15% of kids my age with math. I enjoy math class currently, becaues I am in regular classes, and it is so easy. I have always been in "regular" math, and never had to work ha…

Hey guys, I was woking on my maths internal assesment when I decided to look up soome examples online about my topic (golden ratio on my local city) and I found out that the topis is "overused" and that I could get a bad grade because the topic lacks from creativity. This golden ratio in architecture topic really interested me and even more considering that theres no information about it being used on my city online (Im from Montevideo, Uruguay) so I would be the one that makes the whole progress and maybe, that could compensate tge creativity issue. What do you guys think? Is it really like that? I also have concerns on the mathematical usage as I havent found any cal…

Dear all, For my maths IA I have derived my own mathematical proof of Rothe's formulas for the generation of involution numbers. I did not seem to find any such proofs online, I only found the formulas themselves; I came up with a method for both the summation formula and the recurrence relation, however I am also planning on extending this to applications in group theory and coming up with the exponential generating function. Does anyone know if I would be able to publish this in some small journal? I got the green light in terms of copyright. Thank you!

I was planning on doing my Math AA HL IA on the collatz conjecture and try to predict it. Im using coding to create an experiment sample for Personal Engagement and then create two equations a polynomial equation to predict the sequence and test how accurate it is. The other one is using logs or mod im not really sure and again I test its accuracy. I just wanted to know how good this is or if its too basic because im not sure if this is even right and what else I could add.

Hi guys, I was having a lot of trouble picking a topic for my IA, because from what I know we have to pick a topic that goes beyond the syllabus? So my teacher suggested the topic of Safe and Effective Medication Dosage (Calculus Modelling). It's great because she'll definitely like it, but would the IB? I've been able to find a lot of papers on the topic  she got it from a different program's Calculus book so, yeah, it's fairly wellknown  so I don't know if that would make it less impressive. I'm also not sure whether the topic would let me go indepth enough. It seems simple if I take it just on a basis of dosages, time between them, and time for medicine …
