I think Thushan's currently writing solutions for the scanned copy I sent to him

Was hoping for 45+ too. Messed up the first few marks.... (( Do you guys think the cut off for A+ will be exremely high ? I saw there was a paper once with a 92% cutoff... Dear god i hope that doesnt happen this year. What study score do you think i can get with 115/120 exam, rank 1 97/100 SACs

Any chance you can post the exam on here too, please?

[paper-back]

Then again, this (a really straightforward exam) probably means they'll crack down on worded answers/explanations..

I'm kind of worried now, does this mean that they'd be looking for specific words that you had to include in your answer?

I can post it but the order of pages is messed up - it's in the form of two pdf files with every 2nd page

I'd still like to take a look, if you wouldn't mind.

I'll scan a better copy and put it up.

Same was hoping to get a good score but lost quite a few marks.
For the back titration question about the concentration of ammonia i got in the thousands! Which was definitely wrong and i kept re-doing the question but then couldn't find away to do it! how many marks will i have lost?!

Aww thanks, man!

As a guy who got a C+ for unit 1 chem... that exam wasn't even all that bad. Such a relief to be done, and the calculation-based questions were particularly easy by comparison imo.

Don't worry, I think I stuffed that up, everyone was saying how tricky it was. I didn't find it tricky so I obviously stuffed, haha. but you do get consequential marks as far as I know, so don't stress

Nearly did it wrong myself too because I didn't notice it said to find the n(HCl) reacted in the titration flask (20mL aliquot). So the initial amount of HCl had to be multiplied by 20/250, then you could subtract the amount of n(Hal) reacted. In the end the concentration I calculated was a little lower than the one that was in the information.
Hopefully I got that right...
