From the prospective of a 2nd-year Chemistry student, I thought that this year’s AP Chemistry exam was significantly easier than past years. The multiple choice was like every other year… but the free response was definitely a lot easier.

I did a great deal of past AP Chem FRs… and a lot of them were not as straightforward as the ones on this year’s exam.

1 is a molar solubility/ice box problem that we all have seen <– probably the hardest question on the test

2 is calorimetry - just remember q=mcΔT and ΔH = q/mols

3 I believe this is just a stoichiometry problem? can’t remember

4 the reaction products were amazingly simple - the first one is just the hydrolysis of water

5 the o-chem question was relatively simple. I remember the 2003 exam had a ridiculously hard #5 where you practically had to write the entire procedure for a weak-acid - base titration.

6 almost always electrochem - nothing out of the ordinary on that question. Cathode is reduction, anode is oxidation.

So I don’t think the curve will be bigger than last year… and don’t stress too much if you didn’t get 1 or 2 free response problems - the curve is still HUGE. I remember on the 1999 MC test, 85% of the people who missed less than 23 questions get a 5. That’s almost a third of the entire test!!!
