  1. hey guys i'm in the process of setting an idea for my maths ia and could use some help i have a decent idea about modelling where i model the worlds highest jump and the worlds longest jump. then i will also find the area of both to determine which jump is bigger( idea was inspiration from a video) i could really get your advice and any tips because i have never done a modelling ia before any advice on if the maths would be sufficient and any tips to expand it if not also with desmos am i allowed to autofill a line for me that plots my points thankyou
  2. Im a hl maths student and i wanted to do my maths IA on a topic related to calculus as that was the option that my school choosed. And i came across optimisation of packagings. However ive seen that many people simply use the differentiation method to find the optimum surface area of the cans or products they are investigating. Hence to make it more complex i would want to use a unconventional theory or equation such as the brachistrone theory to find the optimum surface area of a can. Is it possible are there any other theories that i can use? and should i find the optimisation of a can or ar
  3. Good afternoon, IB folks! It is my first year in DP, and only when the first half-year had ended, I realised that I want to change my specialisation. My HL subjects: Business and Management, English B and Russian A1; SL subjects: History, Maths and ES&S. I picked these subjects as kind of evil of the lesser kind because I had no clue what I wanted to practise in the future. Now I'm determined to become a surgeon. I talked to teachers at school and generally (theoretically!) changing B&M and ES&S to Chemistry HL and Biology HL is not that much of an issue (in comparison w

  5. Hello, thanks in advance for your answer. My friend has a very high probability of repeating one year. Under what conditions does a person stay in the second year in ib (11 grade) ? If in the first term (grade 11) the student receives 1,2,2,7,5,6. And in the third term (grade 11 ) he has 7,6,7,3,2,4 + A (TOK) will my friend have repeat a grade ? (Retention one year ) (CAS has done ) My friend is very nervous about this, but I don't know anything about falling conditions in ib. Thank you 😊
  6. I want to do my IA on music (maybe modelling curve using chords) as I am a violinst and a struggling IB student. My interest in both maths HL Calculus and music has bought me till here to do a IA on it. But as of now I am lost about how to start and then go on. And how far is calculus involved and will the IA be a success. I have no idea how to look into this topic and what should I apply it to could I get any advice, resources or any procedures? Please clear my confussions.(much needed of surviving IB🙄)... Thank You!!

    This is a document my teacher gave us to help us understand the exploration' s requirements a bit better. I hope its useful!
  8. Hey, could you look over my subject selections? I want to do cosmology and astrophysics in Uni. Physics HL Maths HL/Further if possible English HL Chemistry SL French AB Business Management SL
  9. I'm a first-year IB student taking Maths HL and our class is currently using the Oxford textbook (the one with the purple flower on the cover). Personally, I find that the explanations/examples are lacking in this book which is a real problem since I practically have to self-study the subject because the teacher is crap. Also, lots of people say the questions in the Oxford book are a lot easier than the questions on the actual Maths HL exam. I have every Maths HL textbook on PDF so getting them won't be a problem. I just haven't gotten the time to reference any other book besides the Oxford on
  10. Is it just us, or do you guys also have Math HL and SL combined classes. The teacher complained about this, but due to everyone's subject choices, making HL and SL classes separate was impossible and it worries me because the teacher goes at a much slower pace during SL lessons and this makes me worried we wont finish the Math HL syllabus in time :/
  11. Hi guys! I would love to know what you think about my IB subject choices. I started the IB programme one month ago, so I still have same time to change my mind. Right now I am studying: English A, French B, Mathematics & Geography - HL Polish A, Biology - SL Could you please tell what you think about this set? What courses could I take at the university level? Personally I have thought about economics, finances, law or something connected with french language. I will be extremely grateful for your help Have a nice day! xxx
  12. Hey guys, I've just realised that my formula booklet is for the 2014 examinations, rather than the 2016 exams which I'll be taking. Could anyone please give me a link to download the 2016 formula booklet? Cheers.
  13. I recently had my first HL mathematics mock exam on topic 1 of the curriculum. It followed the same pace and style of the final exams. Despite preparing pretty well (and for a long time), the test caught me by surprise, and didn't go well at all. The pace especially was very hard to keep up with. From all of you people, I'd like to ask, what are some ways to get better at doing the hl maths exams, how to better prepare for them, and please feel free to give any tips and tricks in general. Thanks!
  14. Hi! I'm in 1 IB now but I made this mistake and took Maths HL. At the beginning of the year I had 3 HLs: Physics HL, Maths HL and French B HL. My school doesn't allow any changes 2 weeks after choosing subjects, but I managed to change also Arts SL to HL as I want to go for Architecture Design. I can't change the levels of Maths but I still got 4 HLs. I'm afraid I will have a bad grade from Maths on exams. So can I write the November session exams (retake) but with Maths SL? I will still have 3 HLs (Physics, Arts and French B). Because if not, I will be looking for A-levels. To have
  15. ---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! ------------------------ Table of Contents Preface and Introduction to the Exploration The Process (to be added) Formatting (to be added
  16. Hi. According to you, which one is the easiest to score a grade 7 in? Maths HL or psychology HL? I'm doing 4 HLs and I wanted to drop one of those two. I'm doing Chemistry HL, Biology HL, psychologyHL and Maths HL. And I would like to study medicine for the future. However I'm not sure whether or not I should drop 1 HL, will it make any difference if I do as Psychology HL is very similar to SL except for some additionals. Thank youuu
  17. Hello everyone, I want to do my Math IA about the nabla (or del) operator used in vector calculus. I'm interested in this because I'm going to study physics at uni and I heard that physics students will need to learn this at uni. So that is a factor that will keep me motivated to do this. However, I don't really know where to go from here. Should I just base my IA on explaining what nabla is and deriving it? Or is there anything in particular I can base my IA on? Thank you.
  18. Hi, I have been trying to do my maths IA (HL), and I did think that I found a reasonable topic. So basically my topic is related to spirographs (maths behind it to be precise). I was initially planning to find the area of the figures of hypocycloids. But then I realised it is already all over the internet. This then seems to be unoriginal (or do you think its fine to proceed?). Now that it looks unoriginal, I decided to twist it a bit and find the hypocycloid consisting of a circle rolling inside an ellipse. But the problem here is, this requires stuff like curvature and elliptical
  19. Hey guys, as you know exams are in less than two weeks and, probably as all of you, I am stressed for maths (I need to get a 7 to meet my university requirements). I think creating a post to share suggestions and useful revision tips would be useful. My main suggestions are the following. 1)Do past papers 2)If you manage to put your hands on the questionbank, do past questions divided in topics. I feel that this technique allows you to understand the typical exercises better than doing past papers. If the questionbank is not available, just scroll through the papers and
  20. Hi, I'm an pre-IB student and I'm considering taking Maths HL. Other subjects I'm taking are: Polish SL, English B HL, Chemistry HL, Psychology SL and Biology, but I'm not sure yet wether on SL or HL, it'll depend on my maths choice. I'm a good student at maths, I get only A's, I took part in many competitions and did quite well in few of them. My teachers say that I will probably manage to finish Maths HL but I personally think I do not have a chance for anything better than a 5, which will not be enough for my university entrance requirements (i'm thinking about something like engi
  21. Hi, Mi Maths HL book (Pearson's Baccalaureate) contains a multivariate calculus question in the options section for calculus, e.g. the P3 section, and I'm just taking horrible amounts of time to finally solve it and I wonder if my P3 is going to require me to solve things of this kind. The question was: the definite integral from 0 to k of (x/(sqrt(k^2 - x^2)) I have had to do partial fractions, several layers of integrations by parts, trigonometric substitutions, weierstrass substitutions, and uncountable other substitutions, and this exercise alone would easily have taken me
  22. Hi Everybody, I wanted to ask whether one is allowed to bring TWO calculators to the IB Exams (only those permitting calculator use goes without saying), the reason being that for the first part of the course I was using a Texas Instrument handheld device and changed to a HP device for the second part, meaning there are operations I am MUCH more comfortable with using one and others I would much rather use the other for. Obviously, I would never be using both at the same time () so it would be like having one, only one that I am entirely familiar with. Thank you! Rebs
  23. Hi everyone!!! I've submitted my first Maths HL IA draft to my teacher and my feedback is along the lines of: would get full marks if: made shorter (it's 10k words but that includes symbols and numbers, that's 30 pages for the body and around 36 including title page, contents, rationale, appendices, etc.) and made SIMPLER I love maths and really stretched myself with this project, going into extensive proofs using topology, logic and more. He also told me to make it so that 'anyone in my class' would understand. I've simplified it, added diagrams with bold, red arrows to

  25. Does anyone have the MATHS HL Papers (1, 2 and 3: Calculus option, preferably) for NOVEMBER 2015? I'll exchange pretty much any paper (2015 May or November) or previous years, if you need them, in BIOLOGY, CHEMISTRY & PHYSICS HL all papers. These are very rare! Thanks! Rebs
