rFumachi Posted November 3, 2011 Report Share Posted November 3, 2011 I didn't do my paper 1 so well, I wish I could have done it better =/. Vectors and planes were my nightmare. 1 Reply Link to post Share on other sites More sharing options...
saunders is god Posted November 3, 2011 Author Report Share Posted November 3, 2011 Couldn't do that bloody boats question, and the vector proofs were sooo hard Reply Link to post Share on other sites More sharing options...
rFumachi Posted November 3, 2011 Report Share Posted November 3, 2011 Couldn't do that bloody boats question, and the vector proofs were sooo hard Same here, section B was hard. I guess that's why I have a predicted 4 Reply Link to post Share on other sites More sharing options...
saunders is god Posted November 3, 2011 Author Report Share Posted November 3, 2011 i got a 7 on the may 2011 paper, but this one was soooo much harder Reply Link to post Share on other sites More sharing options...
rFumachi Posted November 3, 2011 Report Share Posted November 3, 2011 wow! I wouldn't worry if I were you, I'm sure it will get scaled Reply Link to post Share on other sites More sharing options...
zx898 Posted November 4, 2011 Report Share Posted November 4, 2011 I personally find May papers to be much easier than the Nov papers...don't know why.. The boat question....It looks so easy at first..but when u start doing it...the sanity just disappears.... anyway...I got t=0 for that boat question, which is quite reasonable, thinking that the distance between the two was 20 m at t=0. but when t=1, the distance would be the same... but the problem is..I didn't consider any value of t smaller than 1 but greater than 0...so...don't know if I got it right or now... that 'justify your anwser' gave me the courage to put 0 for the first bit Reply Link to post Share on other sites More sharing options...
amy11 Posted November 4, 2011 Report Share Posted November 4, 2011 i half got the stupid boat question. the vectors question, i had done a question on a past paper that was literallly identical, so i got the vectors one. I think i did well for paper 1, but I still found it really hard. i couldnt do the last question, or induction one. I thought the paper was easier than may 2011 but i hope the grade boundaries will still be low Reply Link to post Share on other sites More sharing options...

I thought the paper was easier than may 2011 but i hope the grade boundaries will still be lowreally? how did u go about solving the boat question?I just let x=the time they meet, and set up bunch of equation...and then tried to solve it, turned out to be 0, and for the second part, I got some value so I said they can see each other...I don't know...Erm...the induction one, I was really happy to see that question because there was a question like that, almost identical in the past papers...I think it's 2009 or 2010 May paper 1, but not sure...U just need to solve for P(k)', then just factorize it to get the conjecture for (k+1) Reply Link to post Share on other sites More sharing options...
United4Life Posted November 4, 2011 Report Share Posted November 4, 2011 (edited) I thought it wasn't too bad...Could have been a lot worse.To solve the boats question I used phythagorus for the distance, then found the derivative equal to zero, for t=1/5 (12mins).The parts iii and iv of the vectors question in section b stumped me completely.Also, for the very last question, did anyone else get really odd values the quadratic?Hopefully it was enough!

amy11 Posted November 4, 2011 Report Share Posted November 4, 2011 For the boat one I also used pythag and calc but I got 2/5 = 12:24pm no idea if that's right tho Reply Link to post Share on other sites More sharing options...
United4Life Posted November 5, 2011 Report Share Posted November 5, 2011 For the boat one I also used pythag and calc but I got 2/5 = 12:24pm no idea if that's right tho Yep it is.... I just realized I expanded (20-40t)^2 wrongly as 1600t^2 -800t (instead of -1600t) + 400 Reply Link to post Share on other sites More sharing options...

kj94 Posted January 4, 2012 Report Share Posted January 4, 2012 from where can I get the november 2011 papers ? Reply Link to post Share on other sites More sharing options...
The Economist Posted January 4, 2012 Report Share Posted January 4, 2012 from where can I get the november 2011 papers ?You can buy them from the IBO store once they are released (http://store.ibo.org/index.php?cPath=23_59). Since I believe the results from the Nov 2011 examination session are coming out tomorrow, it should take them about a month or two to upload the November papers.
