I've just had a thought, for the energy change with specific heat capacity question, I put 3,444J but 4.2 is the SHC for water to change ONE gram of water, should 3,444 therefore be multiplied by 0.8 to scale it down to 0.8g from 1g?
You can do it either way, acid into alkali or alkali into acid, it doesn't matter in general, but seeing as you were finding the concentration of the acid...
ISA borderline A/A* C1 A C2 again borderline A/A* but thinking about it, the boundaries will probably be quite high for this paper esp considering the 6marker so most likely on the A side C3 C
i think overall that'd hopefully be a good A
As long as it's an A I'm fine fingers crossed hope you get what you want and same for everyone else out there. And when are the rest of the questions gonna be up!!😅
Does anyone know what the effects are of the ISA grade like a low A* what does it do? lower the grade boundaries for u if ur aiming for a grade A or lower? Thanks!
I got 212 and the bond question and after that they asked for why it was ENDOTHERMIC right? Everyone in my school got that. We sat a different paper coz there is 2 specs Further additional science unit 2, C3( the one i sat) Chemistry, C3 Btw, what did everyone get for the balancing?? Was ethanol+oxygen making water and ethanoic acid?? Or was this question different as well coz i got 2,3,2?
Phew! someone who did the same exam as me, was worried they were the same exam as some questions are similar/same. I also got 212, and 2,3,2 for balancing, thank you so much you've saved my worries

To get an A you need 320 UMS, which includes the ISA and all 3 papers (assuming you did triple).
With the ISA included (90 UMS), you'd need to make up 230 UMS across 3 papers which is roughly 77 UMS, so you need a high B or more on each paper to acheive an A grade
Thanks!!😃 So as I got 45(C1) 48(C2) and 30(C3) plus my ISA of 44 if it's an A and if it is an A according to last years grade boundaries how much marks would I be safe by (I'm still confused) 😂
Am so stupid cos i asked for extra paper in the exam and it asked for the date of the exam..... Guess what i put........ 14 june instead of 15!!!! 😑 Will the extra paper get marked or not?? 😓
