    Blue or black ink?

    As far as I've understood it you must use a ballpoint pen. That's at least what a representative of the IB told me.
  4. I was given an offer for Joint Mathematics and Computing at Imperial College with the subjects you see in my signature. They requested 7 in Maths HL, 7 in Chemistry HL and 5 in English A2 HL with a total score of 41. That should give you an idea about what they want. Also, if you're given an interview they will make you solve problems in order to make sure that you know enough Maths and that you have some problem solving skills.

    You are also not allowed to use gel pens.

    Abnormal psych question

    Your mark will in the end be determined by the amount of knowledge you possess. Therefore, as long as you know your stuff it's not to your disadvantage to pick your 'preferred' two disorders.

    Kinetics calculations

    Were these values recorded from an actual experiment? They're not the nicest values I've seen... I think you were able to see that acetone was order 1. It seems as the hydronium ion also is of order 1, although the ratios aren't that nice. Iodine is interesting though. There doesn't seem to be a real correlation between the iodine concentration and the rate, as I get different values when I compare different ratios for iodine. I suspect that it's of order 0.

    Kinetics calculations

    You might want to fix your list. I can't really see the corresponding rate values.

    Paper II help?

    Both papers really cover the same topics. I mean, both paper 1 and paper 2 are designed with the same syllabus in mind. However, I think the essential thing for paper 2 is to know how to use your calculator inside out. Although both papers cover the same topics, paper 2 is designed with the calculator in mind and thus you get a lot of questions that you need your calculator for.

    Haven't experienced this, but would like to point out that Paper 2 questions can actually ask values not found in the booklet (the lowest p value given in the booklet is 0.50). Thus you have to learn to operate your calculator. Actually, by the symmetry of the inverse probability graph you can find the inverse probabilities for values less than 0.50 manually, using the data booklet. But I get your point.

    So true. This is really the case in Psychology, where the first thing they check is that you approached the command term in a correct manner - then they start caring about the content in your answer.

    May 2012 Exams

    Hmm, I do agree that the 2011 papers were easy. Also, I would say that May 2010 (at least TZ2) was the easiest paper in Maths HL I've seen - finished it in 30 minutes. I've spent these days looking through all past papers from 1995 to 2011 in Maths and there are some patterns I believe. First, November seems harder than May papers which might not be true. Also, in general, TZ2 seems easier than TZ1 (can't complain ) . In terms of problems IB seems to recycle them a lot - I've seen the "Using De Moivre's theorem, show that z^n+1/(z^n)=2cosnx" like 7 times and they also copied a November 2004 problem to a recent paper - only difference was that they had swapped the names of the people in the problem.
  13. What topics have you done so far?
  14. Michel Tabari

    I would suggest doing it manually using the values found in the data booklet. At times my calculator has given me values for the normal distribution and inverse probabilities that are too far off from the correct answer.

    Maths HL Questionbanks?

    You could buy one from store.ibo.org if you've got the money... You could also just ask your Coordinator or Maths teacher.
