  1. Use the Oxford Study Guide if there's one released for the new Syllabus! I used it for my version of the Syllabus (I think it was 2009-2014) and it was amazing.
  2. Sorry if I'm late to the party, but choose Astrophysics. It made me develop a crazy obsession with stars and constellations (hint: look at my name) and some of the concepts have stuck with me until today even though I'm right now studying something completely unrelated to Physics.
  3. It's not hard if you're used to reading Math at a higher level (in fact, it would be introductory). The first section on Linear Algebra is a great introduction to the subject which can be complemented further in college by an Abstract Linear Algebra course (you don't see many proofs in the IB course). The section on Geometry seems tedious (and complicated as well!). On the other hand, the section on Probability and Statistics is very well made. The material seems challenging enough, and it could even be comparable to a Probability/Statistics course taken as a freshman/sophomore in college (sam
  4. If you've seen recursion in Computer Science, both concepts mesh in a seamless way. As the above replies suggest, you assume first that the statement P(n) is true (for given n) PROVIDED the base case is true, to then show P(n+1) is true. Simple example, the sum of all numbers i from i=1 to n is n(n+1)/2. Our claim P(n) (statement) will be that the sum is n(n+1)/2 summing up to n. First, for 1 (our base case), we clearly have 1(1+1)/2=1, so base case is true. Else, assume the statement is true for n. Then, we sum: n+1+(n(n+1)/2)=(n+1)(n+2)/2 Which is our expected formula for n+1. Henc
  5. If you are going into a Canadian university, it depends on what you're looking for. You can get admitted if you have a very high grade in your high school (if you apply under those conditions), and then you can get advanced standing from the IB courses (granted, if you have the required grades to make the equivalent courses be skipped).
  6. I don't think I've got the actual diploma (or it's probably thrown away in the middle of all of my high school documents). They never mailed it to me or gave it to me in an awards ceremony (if my memory serves me right). I agree with the post above. At the beginning I was very glad I did the IB and was feeling super special and smart because I had seen many "complicated" stuff and so on. However, when I got to university I realized that the IB was of little usefulness (although I went into the Sciences and my HLs wouldn't help me for advanced placement credits) as most of my non-IB friends eve
  7. It has happened before. If that is the case, most examiners acknowledge the error and they discount the question on its entirety (or at least the parts of the question that required that incorrect information).
  8. Around July - August. If you are very lucky you can find them online (which I really doubt). I tried looking up exams for my session (i.e. November 2012), and I couldn't see any of them with the exception of Math SL Paper 1. The rest came out around later in the year, when I didn't need them anymore. Some of them never came up, such as both of my Spanish A1 papers or the English B ones.
  9. You can indeed copy-paste a proof if you alter the words carefully or find some variations in the steps required to get to the actual answer. Some IAs don't really require proofs, for example regression analysis doesn't require much proofs (as you have to compare two different quantities and try to develop a model that describes the relationship lying between them). It is hard to obtain a dividing line between Physics and the Mathematics used for it. In most cases, the Math used for the problems can be quite hard, even though it is not the main part of the problem (such as finding electric fi
  10. Personally I never used the graph paper I think. It looks nicer in graph paper but it's hard to determine the proportions you need to use (if you get a more complex-shaped graph). You can just label the inflection and extreme points (intercepts with x or y axis), and I think you would get complete points for that.
  11. The best answer: you have to memorize the case studies by heart (no other way around it). You could try memorizing some facts out of them, but you can forget the rest rather easily with the insane amount of information you have to cram into your head. I would say that you can "prepare" some case studies for each type of question/topics. As well, try to get as much as "multiple purposes" case studies as you can (i.e. case studies that you can adapt even up to 3 different types of questions).
  12. "Pedro Paramo", "One Hundred Years of Solitude" and the other one is a well-kept secret.
  13. Common mistakes: forgetting that cos(x) if x is in the second/third quadrant is negative (or as well the same case for sin(x) in the third/fourth quadrant). As well, know under which conditions a second degree polynomial has real solutions (using the quadratic formula), because lately in the exams they have been asking those types of questions. On the other hand, remember the difference between f(-x) and -f(x) (which is a reflection in either the y or x axis).
  14. You don't need matrices because the IBO for some strange reason thinks that plugging in values and making pretty graphs in the GDC is more important than that (end of rant). But you should know though that matrix concepts are particularly useful in the Vector section of the course, such as how to calculate the cross product. I would advise to just give a quick review of how to find the determinant and dealing with basic operations on Matrices. Besides that, more deeper topics regarding Matrices are discussed in Further Math HL and in future courses.
  15. Your Ib grades are truly phenomenal well done ! I'm simply hoping to pass at this stage haha ! Also you know the simultaneous equation solver app on the GDC is that allowed in exams ?? I think it is, I had a CASIO calculator (I forgot the model) which had the equation solver already implemented in it, so I doubt if they would penalize you for having that program. The most that they can ask you is finding the solution of a system Ax = b where A is a 2x2 matrix.
