Which exam board? I did A level chem under OCR.
Generally I actually really enjoyed it, one of my favorite subjects. The first unit is mainly reaction mechanisms and organic chemistry which is fairly easy to learn and no maths at all. The second unit is the opposite, lots of maths and calculations about entropy and enthalpy and buffers etc.
Look at the course specification to see what topics will come up, but as it's this late on in the academic year why are you asking this question now is what I'm curious about.
