  1. Hey everyone! I've created this topic to discuss about tutoring in IB. I am currently nearing the end of the IB programme (year 12). Through the course, I have come to realise that three of my best subject areas (ranked from most) include: 1. Economics HL 2. Math Analysis and Approaches HL (Since the M21 batch will be the first trying out this new change to syllabus, I might cater to your needs the best if you're a M22 or later candidate. I could also let you know how the final exams would be like once I take it next year if you'd like ) 3. Chemistry SL
  2. I was talking to some of my friends and I told them that my EE was of probability. To be more precise it is of probability on a casino game named craps. My idea was to make an analysis on how the casino always has more chances of winning than the player. My concern is that they told me that this topic is not going to get me a good grade. What do you think?
  3. Hi everyone. I'm having a little trouble with my Math IA., I would like to do the topic "The Mathematics behind Medical Testing", where I would speak about false positives / false negatives and the probability of getting them. However, I don't know where to get data from. Am I supposed to make up a hypothetical situation / disease and then make fake numbers for it ? Is that even allowed..? I would be using conditional probability to find the probability of a student testing positive for the XYZ disease, actually having the disease. I would be using the conditional probability
  4. Hi guys! I am currently working on my Math IA and I am really struggle to find a good topic (I am in Math SL Y2) I think I will mainly focus on population curves in different countries (birth rate and death rate), whether it is more like of a quadratic, cubic or exponential curve, and I asked my teacher and he suggested to use integration and differentiation equations for this topic. However, I am not really sure in which direction can I go with this topic, like what I am proving or what conclusion I try to reach, and how do I apply the concepts or equations of integration and differentia
  5. Hello everyone😄 I decided to write math ia about BMI of women in different countries(especially countries which have really different kind of diets). Do you guys think it is appropriate for math HL ia? Also, I do not know which formula I should utilize to analyse topic... Pleaseeee help me😂 Thank you.
  6. 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 thin
  7. Hi, For my mathematics Extended Essay I am considering and conducting research on the following topic: Comparing the efficiency of classical and quantum algorithms in the factorization of semiprimes I came about this after doing some reading on RSA factorization and discovering the importance of primes and semiprimes, and was curious how advances in quantum computing posed such a large threat to cybersecurity. My EE supervisor (whom although I think is very proficient in mathematics doesn't seem to be well acquainted with this topic) approved my topic first time and found it suitable. Ho
  8. I was doing math EE about finding the least amount of moves in a Tower of Hanoi game with N amount of disks and P amount pegs. Then, I found out that mathematical formulas are not enough and coding is needed to find the answer. Right now, my work contains a little bit more coding than math but I was able to get an answer to the question so I am thinking about adapting it to comp sci by doing something such as writing a program to tell which disk to move, step by step to complete the game etc. However, I've looked up examples of comp sci EE and my topic is very different from them as my topic w
  9. 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.
  10. I'm starting the IBDP next school year and I just submitted my final courses for IB. I chose HL - psych, bio and french b, and SL - math aa, english and chem. Initially when I picked these courses, I was planning on doing Zoology in uni, but now I'm a bit more hesitant on doing Zoology. What major/degree can I get in uni with these IB courses? And what do you think of these courses? (aka what are the stress levels like for these classes). Thank you very much!
  11. Hey guys can y'all please tell me which textbooks are great for the following IB subjects: HL-Phy,Chem,Math SL-Eng A, French B, Business management Thank you
  12. Hi! I'm currently thinking of a good topic for my Math Exploration, and I decided to take "The Handshake Problem" as my topic. However, I do not know exactly how to outline/start my IA. Like, i was thinking of applying the "N choose R" in it because we actually discussed that in class. But, I don't know how to make my IA even more sophisticated from then on. I was also thinking of applying this in a more practical sense, like "how many handshakes in a certain country," but isn't that too simple because i will simply just use the formula? Or, how should I explore the exponential growth (cu
  13. Hey guys can y'all please tell me which textbooks are great for the following IB subjects: HL-Phy,Chem,Math SL-Eng A, French B, Business management Thank you
  14. Writing my math IA and I want to do something with earthquakes, but I have no idea where to start. I’ve been thinking about maybe doing epicenters or the Richter scale but I can’t find a solid way to incorporate them. If anyone has any ideas please reply!
  15. Hello! So I will be attending UWC next year and I want to do a physics major in university in the US or UK. I have already completed 2 years out of 3 years of high school so I already have good kbowledge in math, physics, chemistry, biology, technology, history, geography, french, arabic, english. I am pretty good in scientific subjects so here is my list of potential ib subjects next year: Math HL (further studies) Physics HL English A Environmenal and Social Studies SL (as a social science) French B Computer Science SL Does this list make me

  17. Hi Please help me fill up a really quick survey for my math IA. All you have to do is rate the models honestly! Thank you
  18. I chose bootstrapping in stats as my research topic and I've already done a bunch of research. Bootstrapping requires computer software to run, and so I'd been planning to use Python and some libraries to create a confidence interval. But when I checked the IB EE guide (https://www.shaker.org/downloads/ibextendedessayguide2018.pdf), I saw "Computer programs may only be included (in particular circumstances) in computer science and physics essays." I'm not sure what to do. My topic is quite clearly math, and I'm not sure I can switch it. Are there any exceptions to this rule about computer pro
  19. Hi everyone, Lots of people says that many universities in UK doesn't allows students with Math Studies. However, only Math HL/SL. I've never been a Math person, so that's why I've choosen Math Studies, it's lot easier. I wanna attend an University in UK, most likely England; Bristol, Leeds or other nearby London. I'm planning on studying Law so badly, and my question is; Do you guys knows any Universities in England who allows Math Studies students, that want to study Law? - Nimra Iqbal, Denmark.
  20. Hi everyone, I need help!! So I have to submit my first draft for MathsAA IA soon and Ive been thinking about this. My idea is to model a queue behaviour at a service counter like at a government counter or banks. So basically how many counters should be opened to meet a certain maximum queuing time for each customer? Please give some advice and tell me what mathematical concepts you think is the best I'd appreciate it a whole lottt
  21. Hi, For my math IA, I chose to do traffic flow. So far, I narrowed down my potential questions to: a) How do trucks contribute to traffic jams and b) What causes traffic jams. Do you guys think that one of these is a do-able topic question, or should i change it? How can i structure my IA to get a good mark? Thanks :))
  22. I want to investigate the use of math in GPS. however, I feel like its too broad of a topic how can I make it more specific?
  23. Hello The first draft of my math IA is due in week, and struggle to decide on a topic. I was thinking of using a sin function to model the motion of a ferris wheel, however, I'm a little unsure how to develop my topic and what maths I should include in my exploration, Any help is greatly appreciated!
  24. 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 :)))
  25. 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.
