GabrielBianconi Posted November 7, 2012 Report Share Posted November 7, 2012 Hi guys. I'm doing my IB exams right now. I've done math P1 and P2 already.Can anyone answer me something about FT marks?In the complex numbers question in Part B (P1, it's been way more than 24h), I made a silly mistake about the value of z2 (this was (b) I think) . But this value is used in the rest of the question (19 marks I think , up to (e)). So, even if I lose the two marks for z2, will I get everything else for the rest assuming I did it correctly (using the false value)? Thanks!

Yeah I believe if your method is correct in the following parts of the question, using your incorrect value, then you won't lose any additional marks apart from the A0 in that specific step. Don't worry about it, paper 1 was quite difficult so the boundaries ought to be lower than usual hopefully.Finished math completely now! Relief, haha. 1 Reply Link to post Share on other sites More sharing options...

Relief, haha.Actually, I think that P1 was easier than usual Maybe this is a good sign hahaHopefully I'll lose but a few marks in that question then... Let's see tomorrow my P3 (sets).Thanks for replying. Edited November 8, 2012 by GabrielBianconi Reply Link to post Share on other sites More sharing options...

ANy questions which were particularly hard?P1 was easier than usual, but P2 was harder. P3 (sets) was easy, but you had to work really fast. I mean, really, really, fast.There was less probability and statistics in P1, but a lot in P2. I think most of the syllabus was tested, overall. Calculus was harder than usual, but statistics (distributions) was easier. Reply Link to post Share on other sites More sharing options...
Ezak Posted November 9, 2012 Report Share Posted November 9, 2012 Yeah, you will get points for that. As long as the working is correct, and that the wrong number from before doesn't change the question so that it becomes easier, you will get points. You can only be penalized once for making a mistake like this in a question. Reply Link to post Share on other sites More sharing options...
Lero Posted November 10, 2012 Report Share Posted November 10, 2012 (edited) Would be amazing if you can reply asap Personally, found paper 1 to be quite messy and inconvenient, not very difficult though, but in my opinion more difficult than May. In comparison, paper 2 was much more straightforward and enjoyable, and reasonably simple. Paper 3 (Series and differential equations) was actually really easy but as Gabriel indicated the paper was also uncharacteristically lengthy, and you needed to work at a reasonable pace to finish comfortably. We had to draw like three graphs which is more than the course has ever asked for combined for like all years But it was really fun! Especially the last question with the methodical proof of convergence, partial fraction decomposition, telescoping series and and the limit of x^(x).Edit: And what was up with the 10 step Euler method? That's insanity! How boring... Edited November 10, 2012 by Hus Reply Link to post Share on other sites More sharing options...
Joez Posted November 17, 2012 Report Share Posted November 17, 2012 Paper 1 was very .. unusual. I think the grade boundaries will go down for it. Paper two was by far more standard - the normal stuff were asked. .. But being a maths geek paper 1 was a by far more interesting paper than 1. lol. ..'cept i didn't exactly finish. either of them, really.Sets was a long paper. I got annoyed with the Cayley table with 190759301759027521 {}s. Reply Link to post Share on other sites More sharing options...
