For my GCSEs I revised during the week before, got 11 A-Cs. For my AS Levels I revised much harder, got DEU, (had already decided I wasn't going back anyway, just hated it), dropped out, went to college, doing well and aiming for about 320 UCAS points. When I get to Uni though, I'm going to need to work out a system. I'm not a revising person, I don't think it works that well so I plan to just work hard through the year, learn lots, revise a little bit just to refresh it on the morning and do my best.
