Scientifically challenged

Last Friday I had my Physics practical exam, and today I had my Chemistry practical. It's interesting to contrast them. The Physics exam was 105 minutes, and that was barely enough time to carry out the experiments and write them up. In fact, I messed up one experiment because I was having to rush it. Not to mention the fact that one of the experiments really didn't work very well. By contrast, even though the Chemistry exam was the same length, it was far easier, with experiments that worked first time and loads of time to do the writing up. All very strange, bearing in mind that I'm generally far better at Physics than I am at Chemistry. No more exams now until 17th June!
