  1. 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 for me, I was improving. The next tests I continued to improve and it looked like I could even get a 6 in my IB YEAR 1 school finals. I did the YEAR 1 finals and scored a low 4...something like 39% and I was really feeling bad for myself. I also had physics HL and Econ HL, and I wanted to move to Chem HL, which I later did. BUT MATH HL had turned me to a humble student and I knew I had to work so hard but I couldn't find enough time in a summer that I began applying to the US unis. My grade made me the worst in the class, and also the only student from MYP, so I wanted to blame the easy MYP system but that was not going to help me pass IB...and I knew that! YEAR 2 started and HL MATHS got even more fast paced and harder, and I was literally scoring 2s on Integral Calculus papers, and this was tearing down my confidence. When YEAR 2 MOCKS came, I scored a 30% in P1 and a 38% in Paper 2....THAT WAS A 3 in January whilst my exams were on May. From then on, I got my final predicted grades and it was written on my report I will get a 3 in my finals, and if I work really hard, then a 4. I really wanted to prove that I could get a 6 in HL MATH. So, I began working and revising in February. Going through the IB Study guide for HL maths, IB questionbanks, and an online website that helped with questions. I even got onto whatsapp math groups that I thought could help. When march came around I did a few past papers like worth maybe 2-3 years and sat the exam. I ended up with a 60% in the IB math HL Finals, which is a 5 (StatsOption). Even though I was aiming to show I can get a 6, I will be fine with the 5, because I know I put as much as I could in the time that I had to prepare. From failure, I managed to regain my self-confidence. It was quite a journey of challenges as my teacher who advised me to take the subject had once said.
  2. I'm a month into IB and my classes so far are: HL Maths, Physics, Chemistry, and Arabic B; SL Economics and English LL. However, I've been rethinking what I want to do in the future and have been moving away from engineering/physics towards more Maths and computer science. If I decide to drop chemistry for comp sci, my schedule will be as follows: HL Maths, Physics, English LL; SL Comp Sci, Economics, Spanish AB. My school doesn't offer computer science Higher Level. I'm worried that this setup is not as strong as the first one with regards to me applying for mathematics at Oxford. Also, without CS HL, there is no way I can apply for CS at Oxford and be taken seriously. Thoughts?
  3. What jobs require HL math? Does medicine require HL math? Or does it just look better to have
  4. Dr.Desiron

    Is it doable?

    Hey, so I just made my choices for DP. HL: Math, Physics, Chemistry SL: English lang & Lit, Biology, Dutch self taught. I have a strong background in all the subjects and I need most subjects for university. But....... Did I seriously just kill myself? I mean will I have to stay up until 4am every single night? Is it even doable? Peace out!!
  5. I have been trying to find any idea at all, I want to do it on Calculus. I have tried looking online for ideas but I never really know how to go about doing it on that topic. For example, I saw something on e but I could not think of what to do, the site mentioned that its infinite series contained both sine and cosine, but I couldn't see where I could take that. I appreciate any input or ideas, thank you.
  6. I was thinking about doing my EE in HL maths and found some interesting topics like Rubik's cube permutations, golden ratio and beauty, what 'e' is, what 'π' is, and so on. One of my hobbies is coding (I also do HL computer science and know python), and on one website, someone said that you could involve coding in your EE. How exactly is this done? Has anyone done this before? Thanks, help is always appreciated!
  7. hey guys, so im finished and done with this years ib exams. i just wanted to know how everyone found the TZ1 HL math papers? especially p1 and p3. Compared to last year's papers, i think we can get a relatively higher bell curve, so i'm trying to see how everyone found it.
  8. 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!
  9. So I'm currently thinking of my ib options and wanted to take the following: SL English Language and Literature SL Chinese B SL environmental systems and societies HL Physics HL Math HL Chemistry and I just wanted to know if you can take ess with 2 other science subjects? It's either ess or history and I don't see myself doing history anytime in the future. ess seems more helpful but i'm just really confused on whether or not I can take 3 science subjects in total? also I wanted to know how hard I will have to work if I'm choosing those 3 HL subjects? From what I've heard, taking HL math and physics together is really stressful already, and I just want to be prepared with all that workload
  10. Hey hey hey I'm planning to get a head start on HL Math by working my way through a textbook over my summer break. I currently have PDFs of the Pearson textbook, Cambridge textbook, and H&H textbook. Which one is the best for a clear, thorough introduction to math for a person who is quite nervous about HL math and can a) explain the material clearly (I don't care if its a long explanation- it needs to be good), b) provide lots of practice questions and c) have challenging questions that can test my abilities, similar to ones on the exam? Or is there another textbook that is better? merci beaucoup
  11. Hey All! I just wanted to check, if a question asks us to integrate a function using integration by parts, do I strictly need to follow the formula booklet's formula for integration by parts, or may I use (the significantly faster) tabular integration by parts method? Also, does anyone have any specific tips on deciding whether to integrate a function by parts or use u-substitution? Thanks in advance!
  12. Here's how you can maximize your predicted grades: Use past papers and past exam questions. The IB mark-schemes and therefore your teachers will give as much credit to style as to substance. So make sure you read and practice all past paper questions for your upcoming tests. The style in which answers are written is crucial to getting all the marks. Often, you may know what the question is asking for but only a concise and effective communication method that is often specific to the IB, will get you the full marks. You can get more marks by knowing the style in which questions are answered than knowing the actual answer. Therefore, get access to past papers and questionbanks. Think like a teacher. Thinking like a teacher means looking at the big picture. Before preparing for a test, ask yourself “If I were a teacher, how would I structure a testâ€. Use the considerable resources available on the Internet, such as past papers, questionbanks and syllabi to look at topics and questions that are likely to be on your test because either they are difficult or you have discussed them a lot in the past. The syllabus will be extremely important for you, because most teachers want to cover most of it. Make sure you have copies and highlight important parts before tests. Thinking like a teacher will force you to have a very comprehensive understanding of the topic, which will not only help you improve your marks on the next test but will also predict some of the test. Additionally, this general and comprehensive view of the topic will stick with you till the final exams Befriend your teacher. This may be the hardest and the most unpleasant one but it is definitely the most rewarding one. Befriending teachers means that they have a strong and favorable impression of you. Since the predicted grade is based on the teacher’s impression of a student, it can always benefit you. Being nice and polite in class is always a good idea, but you have to get yourself noticed. So read ahead, read beyond and read about interesting information pertaining to your subject. Find out what the teacher is interested in and create a mutual interest. That way, the teacher will see you as a student who is passionate about the subject. Passion will always take you a 7.
  13. http://www.ibsurvivors.com/new-blog/7hlmaths I would really recommend every current, and prospective, IB student to read this blog post. Are you going to make 2016 your year? What steps are you going to take to bettering yourself? Is this going to be your year? I know it is.
  14. Sorry, I had to use an image converter to post this because the forum wouldn't let me use a certain image extension.
  15. Hi guys! So I have 2 ideas for my Math IA: 1. Tumor growth rate. Hence, it will require mathematical modelling, in particular, topics like calculus and logarithms. I have already researched on a couple of models that are being used. However, my problem comes with this: How do I move ahead? I need an objective to work with for my exploration. With the models that help to calculate the rate of tumor growth in vivo, what can I actually "explore" in order to move ahead with my project? 2. Examining 2 epidemiological (mathematical) models (Reed Frost and SIR) on two real life epidemics (The 2015 Indian Swine flu and the 2015 Ebola Outbreak). I want to know if this is a topic feasible for an HL math IA. Also, will the math be sophisticated enough? More importantly, will I be able to get enough data online? Please do help me!! I AM REALLY QUITE DESPERATE D: D: D:
  16. Hi guys, what are some good workbook/guide book for HL math, the questions in my textbook are too few so I wan to find a workbook that consist of HL math question and possibly with some guidance. Thanks in advance!
  17. Hi Guys Right now i am about to graduate from 10th grade.

And I don't know what kind of folder or binder organization i should have. Also i heard that they assign homework for summer .Did you guys had homework?
  18. Hi! I will be taking the HL Math exam soon and I am confused as to what apps are allowed on my calculator? I have the TI 84+ c silver edition. I have these apps that are preloaded on the calculator: App4MathPolynomial Root Finder/Simultaneous Equation SolverFinanceEasyData Thank you for your help!
  19. Hey guys! I was looking around for textbooks for HL Math and I was wondering which one of the four I should buy? 1. Pearson http://www.amazon.co.uk/Pearson-Baccalaureate-Mathematics-Diploma-International/dp/0435074962/ref=dp_ob_title_bk/275-7064412-8084468 2. IBID http://www.ibid.com....097_mathematics 3.

  20. Hey all! I was hoping that some of you could help me with my HL Math IA, or 'exploration,' as it is now called. I wanted to do my IA over the maths of music, but I've had a really hard time a) finding a topic that might be considered 'sophisticated' enough for HL b) coming up with a rationale/ aim of the investigation. I'm really kind of confused as to how I am supposed to frame my work. Anyway, I think I may have finally found a topic that is interesting, and technically in the HL math syllabus. I was thinking that I could look at the geometry involved in music composition. Take, for instance, the fugue. It has a musical subject that recurs throughout the piece, but the subject may undergo different transformations (it may be repeated (a horizontal translation) or raised in pitch (vertical translation), it may be inverted (reflection), and there is even the option of introducing retrograde motion). I thought it would be interesting to play around with different transformations of a musical subject and see what type of music turns out. My questions for you would be: Is this 'sophisticated' enough for me to, at the very least, not fail Criterion E of the evaluation? And what could I put as my 'rationale' or aim for doing this? Learning about composition techniques? Creating my own unique and mathematical score? I would really, really appreciate any answers, and I hope that someone will get back to me ASAP. My topic is due tomorrow. (Yes, I am a procrastinator. But I actually have been working on this, I just haven't had much luck )
  21. So my school hosted an EE workshop today and after slamming a bunch of information into our heads we have less than 24 hours to hand in our EE proposal. Naturally, I'm still a bit leery on what would be a good idea to do. I'm thinking about doing a Math EE, and this is what I've thought up so far: Topic: The measurement of angles through different systems Research Question: Are popular contemporary angle-measuring systems more useful as mathematical tools as compared with now-defunct or less popular systems? Now I've looked through some Math EE Reports of previous years, and I've noted that my best bet for getting a good mark is probably: a) practical application b) actually doing math I have some ideas about explaining the sources of some systems; degrees, radians, etc; through math, as well as less common ones such as "points" (which is used in navigation apparently- real life application). However, this seems way too simple. tl;dr: My question is this: Does anyone know of any more complex (but potentially understandable for an IB student, of course) mathematics involving angles? Preferably of an uncommon angle-measuring system, although radians and degrees is cool too. Oh yes, also, I'm not sure if this topic is actually any good at all. Any commentary on it would be appreciated.
  22. Hello! I am a Pre IB student and am aiming to take HL Economics next year(I wanted to take Business and Management but our school doesn't offer it). Is it relevant for me to take HL Maths? I am interested in international business/relationship and communication. Considering my current Math grades I think I am competent enough for HL, hopefully. Please share your experience, what does universities look for even? I am confused...
  23. Currently, I am taking Math HL, Physics HL, Business HL and French SL, English SL and Economics SL. I chose math and physics hl so that i would be able to go to the UK to study engineering in university. Im struggling in math hl and dont feel like its for me. My first question would be what combination i should change to, as i also heard that business was not a respected subject by universities. my possible combinations are as follows: HL: Physics, business, econ SL: math, english french or HL: Physics, Econ, english SL: Business, math, french my second questions is about universities. if i want to get into an engineering university in the united states, are those classes enough to get me accepted into a good engineering uni (for mechanical or civil or computer science, nothing including chemistry or biology), even though i dont have two sciences and only one science HL? Thank you EDIT: also , would it help if i took the SATs plus the SAT math and physics subject tests?
  24. This isn't the actual IB exams but.... When I do tests throughout the semester for HL Math, I do really well. I get straight 7s. (tests and exams are based on past IB questions) But every time I do a semester exam, I completely mess up. For semester 1, I messed up on my exam and got a 6(overall semester grade is a 7). And this semester, I messed up as well. I thought I had prepared enough but the questions were ridiculously difficult. I don't understand why this happens. The level of difficulty is just so different. I had never come across questions as difficult as the ones I did on the exam I took today. Will this like be in the actual IB exams? I'm worried that I could get a 6 or even a 5 for this exam. It was this bad. I need a PG of a 7 in HL Math for Economics in the UK and the PGs are based mostly on semester exams. I'm worried as $%^& now. Do any HL Math people know how to deal with the end of year exams where every topic is in a big ugly cluster%^&$? Advice and anything else much appreciated right now. I'm having a complete mental breakdown.
