Depends which subject and also depends on the day... some days I'm thinking 'yeah I've got this covered' and other days I'm having panic attacks and convinced I'm going to fail.
Sociology, I'm the most confident about if I'm honest. With revision I think I could actually do quite well and MAYBE get the A I need for university.
Psychology, I have the essay/question structure nailed but I have to learn the studies. Once I've done that I might be okay.
Film... don't mention Film to me *hides*
