  1. I am going to start the ib next month and I wanted to know what previous knowledge I need to have of math and chemistry so I can start preparing myself in these two subjects before the start of the year.
  2. Hey! What do the CalTech Admissions people look for in a candidate? How do I maximise my chances of getting in? Any CalTech Alumni here, I would love your advice.

    MATHS IA HELP - TIDAL WAVES?

    I have currently chosen to investigate tidal waves for my maths IA. However, I am unsure as to what other explorations I can do under this. (And whether or not this is too simple...) Is modelling and predicting future tidal waves appropriate? I have secondary sources that'll give me data of tides at different points in times at a beach, so I will be able to graph them. I will also use trig and algebra to find the ideal time to visit the beach with my "ideal" tidal height of 1.5 metres I am uncertain as to what other maths/exploration I can apply to this Any suggestions would be greatly appreciated!
  4. URGENT HELP REQUIRED PLEASE I want to do a world studies essay with Computer Science (which I don't study, but will at uni), but I'm stuck. I had planned on crossing it over with economics (one of my standard level subjects) and doing it on the Cambridge Analytica scandal, but my idea doesn't have enough econ in it. I would love it if there are any ideas crossing it over with any of my subjects: Maths HL, Physics HL, Spanish HL, English SL, French SL, Econ SL. I have to get back to my advisor by the end of the week!
  5. I was thinking of doing my Maths IA in statistics, specifically something related to psychology, e.g. What is the relationship between mental illness and crime? Anyone have any other ideas or examples for a statistical IA that incorporates a psychological element?
  6. Hey! I was wondering if anyone has done a Maths IA (exploration) connected with sport and calculations around it, can be both HL or SL. I have to write an essay in Maths (for a competition) which is somehow similar to IA (but it's not really about IA), so that's why it doesn't have any specified level of Maths required. I was thinking of calculating something with skiing (or figure skating) cause I'm interested in that and I think I could find some Maths in it. However, I'm not sure how to tackle the topic (I'm in Y1 so we haven't started our IAs yet) and what it could possibly be about. If anyone has done an IA (or another Maths essay) in any of these topics, it would be awesome if you could tell me what you did basically 😀 Also if anyone has any good, interesting ideas (not neccessarily connected with sport) and rather difficult ones (since it is a competition), feel free to share them with me! I just need to find some inspiration on what I can research and write about. Thanks in advance!!
  7. Hi, My maths IA plan is due in a week and I am having trouble figuring out how I could further my investigation. My idea is to apply calculus and the principle of Optimization to minimize surface area to volume ration of a house. Does any one have any good ideia to how I could go beyond finding the optimum surface area to volume? Maybe an additional area of mathematics would be good. I would really appreciate it if someone could help me. Thank You
  8. Hey, I started IBDP Year 1 in September and I've chosen Maths SL Analysis & Approaches. I'm now experiencing some difficulties (as majority of my classmates) because we had a very bad Maths teacher last year. I was always quite good at Maths and that's why I decided to choose AA. However, now I'm considering changing from it to Maths SL AI. I want to study medicine in the UK in the future (I'm dreaming of studying at the University of Oxford or University College London). My question is, is it much better to have Maths SL AA than AI. I checked the universities' websites and they don't say that any of the Maths levels is required for medicine. However, all my friends say that it's actually better to get a 5 in Maths AA instead of a 7 in Maths AI and I could stay in Maths AA class and I can't really decide what to do. Thanks for all pieces of advice!
  9. Hey guys! I just started IB1 and i’m having my mock exams soon. I’m finding IB hard (Because im not naturally intelligent) and I keep doubting myself. So many people in my school are redoing IB1 and I’m scared to see myself in that situation. The subjects i’m taking are quite difficult. HL Chem & SL maths AA especially my question is, suppose I dont get the requirements needed to be promoted to IB2, Will I be forced to redo IB1 or will i have the opportunity to resit some exams and do extra work during the summer?
  10. Hi, I need an urgent help for my math IA. I have the attached graph, for my set of data. I need to find a suitable function for it and I really cannot find correct one. I tried to split the graph to different parts but the teacher said it won't be good. Therefore, if someone knows how to find a function for this graph I would be very thankful. Thank you in advanced :)))
  11. Hi guys, I’m currently working on my Math SL IA and I need help on what maths to use. I am investigating the variables affecting reaction time, such as sleep, gender and involvement in sports. My teacher approved my topic, yet he said simple statistics would not be enough for an SL IA. He said I could calculate probabilities from the distribution graphs, but I’m not sure what he meant. If anyone could explain how I could use probabilities and give me more ideas on what maths I could apply in my investigation, I would really appreciate it.
  12. Hey, Anyone starting IB 1 in September 2019, what are your choices? I'm taking: HL Music HL English Literature HL History SL Maths SL Italian SL Physics
  13. 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 😊
  14. Hi! So, I have been thinking of possible Maths IA topics for quite a while and have just decided to do it on Vectors (because I'm relatively better at it?). I have heard that quite a few game developers utilise vectors during the game development process, and so it would be in my greatest interest to base my IA on vectors in video games. However, I'm not quite sure on how to go about writing this. I have a basic outline of the structure of my IA (start with 2D then advance to 3D), but I'm starting to worry that it may not be as good as a topic as I hoped it would be. Could someone tell me if this is a feasible topic? What should I do to maybe add more depth to this investigation? Thank you!
  15. I have been struggling with my Maths due to how I was changing schools twice before, in and out of different systems and I really need help with the syllabus now but also some of the basics from before. Does anyone know where perhaps online that I may get free tips or help on my maths?
  16. Hii My IA idea submission is due tomorrow and I have no idea what I really want to do, but came up with the idea of optimization using differential equations. I thought of reducing the surface area of packaging in different shapes like sphere and prisms, and calculate the minimum point (minima) through second order differentiation equation. I am also planning to then apply this to different real life examples like Toblerone triangle prism or something like that. Do you think this is too simple at the level of maths HL because it is just at the level of maths HL in the syllabus? I am ready to discard the idea if the maths involved is too easy for HL. Thanks xx
  17. hi... I took May 2018 exams with 4 HLs( maths,chemistry,physics and EngB) and got a 4,5,6,6 in each subject. I missed Nov 2018 exam so I am thinking of retaking( I mean I must..lol)only maths or both maths and chem in May 2019 I want to change HL maths to SL to get more points. Is it possible to change the level for retake?? Should I retake chem as well? my grades are maths hl 4 phy hl 6 chem hl 5 eng b hl 6 kor a sl 6 b&m sl 6 2 bonus =35 Will there be enough time to do the IAs and exam preparation for both maths and chem? or should I focus on maths?? Thank you!
  18. I don't know if I can do research based on just the mathematical analysis and interpretations of a physics concept for my EE, rather than conducting any sort of experiment or data processing. My teacher says the IB won't expect a theoretical/pure mathematical paper. Is that true?
  19. Hey, I don't have a lot of time and I'm desperately searching for my EE topic. I've been thinking about applications of continued fractions or looking for the best way to define pi number by probability. I dunno what to do with the first topic to show my personal engagement and I'm not sure whether the second idea isn't too simple and should be used rather to write an IA. Can you comment on them and/or eventually give some ideas? :/ I feel like committing a suicide but I like this subject... Any tips to survive?
  20. I am interested in selling a number of my IB books (many of which have never been opened or used, although some have plastic contact on them)! I took my exams in November 2018 so these were the books that were suited for my year and possibly for future years to come! - Edible English 4th Ed. [BRAND NEW] = $20 - Biology Study Guide Oxford (2014 ed.) [BRAND NEW] = $70 - Biology Course Companion Oxford (2014 ed.) [BRAND NEW] = $45 - SL Maths for the IB Diploma Haese 3rd Ed. [BRAND NEW] = $70 - TOK 2013 Ed. Oxford [BRAND NEW] = $50 - Extended Essay Oxford Course Companion = $40 - Economics in a Nutshell Exam Study Guide Tragakes = $40 I would prefer to only send stuff to Australia but if you are from elsewhere just let me know! Thank you and good luck with your IB studies!
  21. "To what extent was the cold war responsible for the separation between North Korea and South Korea?" is this too broad? please someone help how i should phrase my research question. I really do have interest and a lot of knowledge in this area (the Korean War) & (The Cold War)

  23. Is finding the derivative of trigonometric/circular functions, like the sine and cosine functions, part of the Math SL syllabus? Is this the level of Math SL or is it more advanced? I'm thinking of doing this in my calculations for my IA. Would it work?
  24. Hello I take maths SL and my homework for the winter break was to come up with a topic for the IA. I'm considering f/stops in photography which has something to do with geometric sequences and some mathematical explanation why these stop numbers make sense. It seems good enough, I guess, but my concern is that it's not very authentic. May I have your opinions, please? Hadassah
  25. I've been asked to come up with an IA for Maths, and I was thinkng about combining a topic with DT as I wish to do product design at university. If anyone had any idea big or small it would be very useful.
