  1. I have found everything alright, except for science multiple choice papers - both HL Physics and Chemistry were noticeably harder than previously. HL Maths - there was one very tough but one (relatively) easy paper - that equals out I guess. Apart from that, to my knowledge ALL language B papers have been very tough so far - I blame those of you who take language B in your first language - it makes it impossibly tough for those who study a foreign language and play the game honestly.
  2. This is interesting, firstly because I said acid anhydride and you're the first person to have said the same!! In hindsight, both are possible so I don't know what they will do regarding that. I also struggled on the acid question for the same reason and I wrote exactly what you wrote, but my friends have said that the question regarding acidity was referring to the hydroxycarboxylic acid from one of the reaction processes if I can remember correctly, or at least not compound C, which I didn't notice at all in the paper. Can you remember anything else? Perhaps they worded the question poorly and it wasn't entirely clear upon reading first time round... I thought I just made a silly mistake but I'm intrigued that someone else seems to have done the same... ... That final double page was generally not very nice!!

I need every mark possible

  4. Which question was this? The one that had Mr = 44 Cool, I seem to remember getting A too.
  5. Which question was this?
  6. Are you TZ1? Because I'm TZ2 and found relativity more straightforward than astro..
  7. Last one I'll bother you with, the question regarding which combination would form a buffer? I picked the one with weak acid 20cm^3 and strong base 10cm^3, or vice versa if it was an alkaline buffer.
  8. Both molecule requires two functional group on each side. -COOH-R-HOOC and -OH-R-HO- That was the II statement but III was right too with H2N - R - COOH and another H2N - R - COOH because they have two functional groups (and these are in fact amino acids that condense to form long polymers that we call proteins Its covered more in Option B) so it was the option that had both II and III YES! Thank you for that. I need every mark possible after my tragic paper 2!
  9. Wait you're right. I wrote ester but now that I think about it, that does make an acid anhydride. Oh well I think they'd give a mark for ester though? Because the ester linkage (COOC) is still there I hope they will give a mark for both! It was an odd question I thought, slightly beyond the syllabus and difficult because you could attack two different OH groups. Oh well, only 1 mark
  10. Hey guys, found this one pretty good but I crammed my ass off the night before, I knew I needed to after paper 1 and 2. I did options A and G. Can any of you remember what you got as structure C on the last question? Product of acyl chloride and hydroxycarboxylic acid? Allegedly it was an ester but I managed to manufacture an acid anhydride, just wondering if anybody else did that too?
  11. I wish I could put my mind to rest about this but I cannot. Can any of you recall your answer or the question regarding which polymerisation process was not possible? In P1 TZ2
  12. I said the same thing. 107 for one and <120 and<180 for the other one.both had a lone pair. What did you writr for the question were they asked about the covalent bond between hydrogen and carbon? So the bond angles for the seesaw should be more than 180 so 186 because of the pair of lone electrons that has extra repulsion, less then 120, so 116 and exactly 90 so 186,116 and 90. I was blessed with this question as I wrote all of the shapes and bond angles on paper night before the exam and memorised I think that Pearson's HL book is great for learning bonding cuz in Study Guide they do not pay attention to shapes and bond angles. Damn, you are right What did you guys get on question 7 I believe, on the PH for ammonia solution or something like that? The bond angles were tough, for the see saw! I got a ph of around 11 I believe.
  13. I got a 41%.. But the answers 44% I made a stupid calculator error while entering the inputs and ended up with the wrong answer Hopefully I won't lose too many marks.. How should I calculate the area ? I got a 41%.. But the answers 44% I made a stupid calculator error while entering the inputs and ended up with the wrong answer Hopefully I won't lose too many marks.. How should I calculate the area ?You drew the 4 by 10 rectangle and the goat was on a 5m rope attached to the corner. The goat could cover an area up to the arc of a circle with radius 5m and centre one of the vertices of the rectangle. Then you could split the area into a sector and a triangle and you could use the triangle to work out the angle of the sector, easy from there.
  14. When you log in on results day, you will see each subject you took and the overall mark for it, your total score, and whether you have received your diploma or not. Your ib coordinator receives the breakdown for each student a few days later, at which point you can ask to see your component grades for each subject you took. Thanks! When you say "mark", do you mean 80/100 or 7?
  15. I got this exactly really 27 ml? i thought it should be 30ml lol, as it was the highest temp? yet I know it it is that simple, IB wont even tell us to draw a line though. Btw, for TZ2 pp1, I didt rmb clearly if it is 1 mol of hydrogen atoms or 1 mol of hydrogen gas. if its atoms then ans shud be C . It said 1 mol of hydrogen gas and the answer was D, I am 100% sure because I was aware of these questions after getting them wrong all the time in past papers. Also, I do actually remember the first question on paper 2 said "determine the volume by drawing lines on the graph" because that instruction probably saved me. Thanks for your explanation. This affects part (b) of it too. Hope ECF applies. It better Or we're screwed for that question hahah that was a tricky one, btw did u know the answer for paper 1 question 2 abt combustion? I filled in B. It was the one with 3y/4, whichever one that was
