  1. I do agree!! I found it to be such a relief... One question, for the bacteria question 8, when they said after how many nth hours is (A) greater than (B), did you write 5 hours, or 4.78 .... What I undertood is that they wanted full hour. I can't remember :/ Sorry! For those of you who did get the binomial expansion problem, did you get K = 2? Hey,, yes for the bacteria question I answered 5 hours as well as they wanted full hour (I got 4.something something, but as they want the pop. to exceed so yeah) For the binomial expansion, I got k= 2
  2. Hey,, I'm doing chem HL too I think that you shouldn't concentrate too much on past papers (although it will help guide you). Try to look at the objectives for each of the units and check on yourself whether you know the answer to it For the exams, my teacher told me that usually there will be quantitative chem for first question in ib paper. Also, try your best to concentrate on organic chemistry as they usually put huge proportion in it for paper 2
  3. hi i did that at first, but i realised it wasnt an integer. so basically i dont think you need to. since you had s2 you know that u2 is s2 - u1 did you do that? and what did all of you write for the general expression? i just added the arithmetic sequence with u1=1 d=3 to the geometric one with u1=k r=2 or sth Safe to say, I messed up on that one, my brain wasn't functioning properly then (started with section B). Ah well, aiming for that 5. i wrote it the other way around because f''(-2) was negative? since f'(x) was decreasing so i had f(-2)<F'(6)<f(0) yeah I found d = 3 and k = 0
  4. Hey, did option D as well. I think it want to say about how tetraploid is formed and can't breed with diploid as the offspring will be triploid which can't do proper meiosis

  6. The paper was quite good for me, although not sure about the Un question I found square root of 65 I also got root 65
  7. Was the best paper compared to the other two for me haahha did option D and G here
  8. I wrote habitat degradation and lack in food supply haahha
  9. awww hahaha I think I kinda mess up that one too, not as bad as yours though o.0 but I think you can still get 7 even if you mess that ques??
  10. ahh sameee! Mostly only explain about the protagonist's reaction toward Finn hahaha :/
  11. oh yes i also wasn't sure what they were referring to by the ''dynamic nature of resources''. perhaps, they are referring to its various uses or to the different viewpoints on the management of resources? I'm not quite sure on that too, but I think they means how the value of the resources change over time? hahaha
  12. I answered the oxygen one, not really sure either hahaahha but i was thinking its "aerobic" bacteria and that photosynthesis produce oxygen so >_< That there is most photosynthetic activity at 450 what not nm and that the aerobic bacteria like that I answered the complementary base pairing for the DNa conservation hahaha
  13. what did u guys answer for the phagocytes one? in paper 1 >_<
