Pssh i honestly dont think i got anything wrong, its just that the criteria often gets quite anal, quite fast and you end up with 0/100

Maybe 90+

I just guessed the first in industrial chem using logic.. It said that it was in a sealed container, ie to keep something out (Moisture). It said it was hydrated copper sulfate... 2+2... maybe its a dehydration reaction... Conc H2SO4 :)

Even for the last reaction, hope you put catalyst AND temperature increases reaction rate (But not yield ofc)

True, and ive asked many chem teachers about this, they have all said assume bromine water = Br2 Quoting off wikipedia For example, reaction with ethylene will produce 1,2-dibromoethane. Bromine also undergoes electrophilic addition to phenols and anilines. When used as bromine water, a small...

Its a band 6 And no, state rank each is 95 raw and over

Not to boast but just to share info (I think my MC was all correct, but please correct me if i am wrong) 1.A 2.D 3.C 4.D 5.B 6.A 7.B 8.C 9.A (In answer to poster above, its A because its polar nature allows it to form dipole dipole bonds and thus is soluble) 10.C(Remember rules) 11.D(If it was...

I talked about Solvay, Frasch and NaOH as a whole (Ie, social impacts stemming from all three different cells) Think i would lose marks? Oh and i didn't even outline the process. Only gave like 3-4 social impacts for each. G to the G

Best case 81 or so

Re: Anyone else noticed how easy it is to get away with writing after the exam's fini OP what do you estimate your mark to be anyway?

What a timeless, pro statement ^^

I do 4U and found that quite challenging time wise. Prob 78-82 out of 84 For P it was some wierd ass answer obtained from quadratic formula. All i remember was a fraction with a -sqrt17 in it tho..

Only got this question because i learnt what the reflection theory was in physics.

What you checked 60 times and your sure is right could still be wrong if you follow the wrong path of logic each time. Theoretically, you could get 0 for the entire exam

Best i can get is 96/120 :S Much harder then last years.

The grade went half half

True it did start in only 2008, but someone found a precedent for a different but similar module (Ie 6-7 core texts where they specified which one you had to refer to)

Sydney boys

Lol mod B was great. Someone found the 2002 HSC paper where they specified a text, so our whole grade prepared for every Orwell essay, just in case.
