  1. Question 1 was basically where f(x) = (ex + e-x) / 2 ) and g(x) = (ex - e-x )/ 2. They tell you that f'(x) = g(x) and g'(x) = f(x). Basically it asked to integrate (from zero to infinity) g(x) / ( f(x) )2. Basically you just needed to substitute u = f(x), thus du/dx = g(x) and dx = du/g(x). The g(x) cancels out and you just needed to integrate 1/(u2). Solution on Wolfram Alpha. I got (lnx)2 for the integrating factor. I said that the interval of convergence was -1 ≤ x ≤ 1. Solution on wolfram alpha. I got that integrating factor too! And I got that radius of convergence too! Did you also get
  2. For me, paper 2 was the best paper that could ever have come up. With questions on Weimar, Mao's policies and the wartime conferences, I couldn't chose which questions to do - they were all great! Paper 3 was a different story, where none of the things I studied came up :/ It was a tough paper for me. Did anyone else think that the sources in paper 1 were weird or was it just me?
  3. You should expect a zero. If everyone wrote on whichever topic they pleased and disregarded the questions, what would even be the point of setting questions?? The examiner will assume you do not know anything about the February Revolution, have only prepared for the October one and pretended to have misread the question. Imagine if everyone just changed the name of the single-party leader in paper 2 as they please, or changed for example the essay question from 'discuss Alexander II's policies' to 'discuss Nicholas's policies' in paper 3. How did you not read the question properly?? Hopefully
  4. This was by far the easiest of all the papers. I LOVED it. Nothing unfamiliar, nothing unexpected, and plenty of time to finish it. There was not a single tricky part to it, and I am surprised that you found it tough if you had no trouble with papers 1 and 2, which were a lot more difficult. Why didn't you look into Rolle's theorem? And how couldn't you do the improper integral? Or radius of convergence? This was all standard stuff!
  5. I am glad I was not the only one who got 0 for the gradient. I just wish I had written that, I would have gotten one more point :/
  6. I thought it was awful, considering that it was focused so heavily on functions! I needed at least half an hour more to finish the paper :/ During the reading time all I could think about was how there is no end to the paper and how the questions go on forever. I am sure the grade boundaries will be very low though, especially considering it was the first year of the new syllabus.
  7. Hey rpatel9, I did pick that section, I thought it was alright since I didn't find it too difficult too compare and contrast the two texts. Identifying and analyzing the linguistic/stylistic features was a different story though. I don't know whether there are a limited number of them or just that I failed to find them. Overall, Paper 1 was a 'meh' for me, expecting neither a good or bad mark. By the way, which question did you pick for your Paper 2? I chose number 3; the one with plays being staged, poems being read aloud and books being turned to movies. Anyone else chose the question, maybe
  8. I did the second question in section B too! And I also couldn't figure out the last question because I didn't know what the length of the tube was... Because mass per unit length does not give you the mass of the tube, right? Apart from that, I thought the paper was good. Much more difficult than previous years, but still manageable if you were well prepared for it. And I finished early ^.^
  9. I am not sure if this is just a coincidence, but all the people who are really good at music (not talking about singing here, I mean reading notes and writing songs) at my school are in math HL and one is in math SL. The people in studies are applying to courses like fashion, journalism and literature. You CANNOT get into a good economics course if you are in math studies- the best universities in England require a 7 in math HL for a pure economics course, so forget econ right away.

    Does anybody have any kind of revision material on Nyerere's rise to power? He is valuable to know for paper 2 topic 3, but all that I can find in my textbooks are limited notes on his policies and his consolidation of power. I'd appreciate if anybody could tell me anything specific that can be used as a strong argument in his contrast to, for example Hitler or Stalin (even Mao)?

    As long as you use the key history terms, it shouldn't be a problem. I did mine on the impact of a political system transformation on the economy and my teacher liked it. I also thought my topic is too economics-related when I first did my research, but as you get into it it should start getting a "history" feel.
