I wonder how accurate Matrix is compared to Jazz lmao their marking is so easy (apart from enthalpy and entropy) my marks rise by like 5. It's the difference between a low and high band 6... considering NESA is nice enough that only one question is marked on sig figs. Jazz a real legend but I'm...

I'm trying to look at raws from the raw mark database but the discrepancy is crazy tbh. In one year some of them have got a 3 mark differential (i.e. 85 vs 88) scaling up to the same high thing (93-94) and idek how that's possible

Wait, are you sure we need diagrams for the boiling point question? What if I gave a lot of analysis about hydrogen bonds and permanent dipole-dipole forces in depth :(

I don't know what this means :( like as in, they choose one specifically to be marked with sig figs in the criteria? But thank you for the reassurance!!!!

I can tangibly feel myself losing random marks through sig figs

Thanks for the answers! Omg Q.18 I honestly flopped akaksksksk how'd I not see the x 10-4!?!?!? SO blind I also totally flopped in evaluating Bronsted-Lowry theory, didn't realise I was gonna lose a mark but obviously I needed to have included a limitation. I didn't. Smh! I'm actually...

omg wait I'm really grateful for answers and don't want to be presumptuous but for multiple choice is it okay if you put the answer in words/number too along with the letter? i just realised i don't remember anything i picked thank you sm

Omg thank you! Early MCQ whew I can finally look over everything and stop stressing

omg y'all i just realised matrix releases all solutions on their blog lol. thought it was just bio but nah maths, chemistry, everything chem is not out yet, seems they're gonna release solutions once NESA uploads the paper? but yeah, i guess we can stop thinking over everything cause we'll have...

I meant HF on the left OMG and don’t worry! I might not be good at Chem but my friends are and it’s kinda sad we all reasoned wrong LMAO. If you remember the acid as CF, undoubtedly that is a stronger acid regardless of what else is in the question. Now, no more procrastinating for physics! My...

Me expecting my IPT from two years ago to count in HAHA This just means both me and all my friends misread OMG embarrassment! I concede defeat. I do remember the equation tho - equilibrium with HF on the right, other acid on left. Idk why I remember the constant was 3, maybe that’s just placebo...

I think we just need the paper. I’m totally blind (I do remember a higher than 1 constant tho) and I asked two of my friends and they got the same thing, so I thought it was acetic. You guys know your stuff though and both of you got something else, so we could’ve just all misread the question...

can someone please explain why it was possible for the equilibrium constant to be 3 if the other acid was stronger? it lied to the right, i.e. concentration of products greater, and i thought that meant HF ionised to a greater degree than the other way around, because the other acid was on the...

omg wait i think it's because i mistook CF3COOH for acetic acid? OMG AKSKSKS THAT'S SO SAD I'M SO BLIND WTF ive officially done better in eco multiple choice i didn't know this was possible

I got D :( strongest acid HF and strongest base CH3COO- it's okay, now when i think about it i answered part 1 of that AAS question really badly. all i said was they form precipitates, i didn't even talk about how one metal has a higher ksp than the other etc. etc. yep, i'll defs need to stop...

i don't have answers so i can't check :( for strong acids and bases basically it was one of the last four right? i was desperate so when i was up, signed and walking out (please don't begrudge me lmao i was literally leaving) i just chucked a glance at the smart girl's sheet before me - only had...

omg i can't believe it yes that's such an obvious thing! i'm so dumb hahaha i got caught up in the silver mirror whatever. like, aldehyde reduces the ions to silver and ketone remains unreactive. now that i think about it, i wouldn't be writing equations for that either so hope they don't...

OKAY haha i got that too can't remember all the other MC i felt were sucky so guess i'll have to live in suspense until december 16th last thing - i remember in the very first q they were asking for a test to differentiate between the aldehyde and the ketone lol... vaguely remembered tollens'...

so lol... that difluoro question in the multiple choice? how many carbons in the molecule? anyone sure of their answer for that? only 2 numbers i remember are 750 and 1500

fingers crossed! haha i didn't know this thread existed before, it's cathartic to discuss a few questions with everyone the day of the exam, by the next day it's indeed better to not dwell on it. i'll keep an eye out if anyone has any other questions to discuss. good luck to you for physics...
