Hey. First things first, stop worrying so much! This may well be what's stopping the revision going into your head, because when you're stressed, it's extremely difficult to concentrate. I know that GCSEs seem like the be all and end all of everything, but they honestly aren't. The most important thing is that you just get enough to do sixth form (if you want to). Also, remember that GCSEs are written so that the average person can pass... otherwise there would be no point in making them compulsory. You're teachers aren't fools - they've obviously seen something in you that has made them think that you're significantly more intelligent than average (if they hadn't they wouldn't have predicted you such high grades) and so tackling something that is written for someone less intelligent than you to pass in shouldn't be a problem. Yes, it probably would have been a good idea to revise earlier, but you do still have time. What I would do, considering you don't have a whole load of time, is prioritise. The subjects that you got Cs in probably need a fair bit of your attention (if you don't want Cs even though they're perfectly acceptable), so focus on the subjects that you find hardest, have more content and the ones that you want to do particularly well in. Write up a revision timetable so that you have a plan of how you're going to go about your preparation and then write notes. Once you've done that, do an activity that makes you recall what you have learnt as this is the best way to consolidate information (for most people). This may be making your own question cards, going on a revision app/website or explaining it to others. I'd also recommend doing as many past papers as you possibly can (another fantastic way to get the info into your head by recalling it) and then mark them with the mark scheme so that you can see what the examiners are wanting from your answers and where you might be going wrong. At GCSE, it's unfortunately just a bit of a game of giving the examiners what they want, so make sure you use the mark schemes to brush up on your exam technique. Obviously, these tips that I am giving you are just my opinion, so don't take them as gospel. However, following this procedure did help me to achieve 5 A*s and 4 As even though I was seriously unwell for all of year 10 and most of year 11, so they work for me!! All the very best in your exams. If I can help you in Biology or RE, don't hesitate to message me and I'm always happy to lend a hand. Best, Izzi.
