Im ranked first and think i got maybe an 86-67. But could also lose a couple more depending on how cruel they are with the written stuff. Possible to get a B6?

it was actually 0.39. A lot of people got .53 which was basically the correct solution but forgetting a line (had to account for ions in solution)

surely someone has solutions up by now?

Yeah probably 3. would be 4 for getting the first two correct but -1 for swapping the halide. Did you write anything about E or what it can/cant be? bc that will sometimes get you an extra mark

probably lose 1 mark for swapping Br with F ( they should be able to see what you meant to do but cant give you all the marks obviously). maybe 3 or 4 out of 7 in total if you didnt get anything to do with compound E? idk really tho

Often for a 4 mark calculation question you can get 1 mark for 'some relevant information', 2 for 'provides some steps of the calculation', 3 for 'provides most steps of calculation' and obviously 4 is getting it correct. So i would guess you would get a mark. probably 3 for those of us who...

what did you guys get for 25 (phosphate ions)?

think so. either that or 2-bromo, cant remember which way round it was

i just talked about 1 (i think the one with 6 H nuclei in it and was a doublet). it only existed in one of the two possible molecules i think

yeah thats pretty much what i did. i just hope they don't say you have to go over the titration bit for full marks bc you didn't need it and so i didn't use it

lol i just drew the two possible structures for E and looked at one of the peaks and showed how it only exists in one of them. I thought about adding the titration stuff for all the compounds but really didn't want to bother so i didnt

Q35 was "Identify which structures 1, 2 and 3 in the table are acids X, Y and Z. Justify your answer with reference to the information provided." Surely we dont have to refer to it all, they gave so much info that you didn't really need

guys i think i only got a 99 raw😔 i coloured the wrong circle on q17 but had the right answer in my head. idk how i did this badly am i cooked?

Which papers from 2019-2023 do you guys think have been the most difficult?

not too bad, found Q14 harder than i should have tho. What are we thinking for alignment?

Was it 2020 that the current syllabus started? I just want to work out which papers will be fully relevant to us

i hope so. i have no clue how to any of the probability related stuff bc it puts me to sleep. i just end up doin E2 in class when we were doing it

Atar Notes has some revision lectures that can be helpful to go through each topic and remind yourself of what is involved and try some practice questions. Good for exposing big areas of weakness. mcgrathematics has a playlist of ext. 1 topic vids on yt. havent used them much personally but...

Ah right makes sense, thanks

Wait what kind of calculations do you need to do? Like is it just a formula for entropy? I haven't done this stuff for ages so im a bit rusty
