Thank you OP for posting useful information to help other GSCE students.
I too have finished my GCSEs and have achieved 9.5 A* and 1 A (
short course counts as half a grade, not a full grade), as well as an A in an AS level subject.
My revision strategy for science subjects:
1. Find the relevant specifications, print off a checklist and highlight the parts that you are unsure about.
2. Look up relevant parts on revision guide/text book, and make short concise notes (one that meets all the marks in the mark scheme)
3. After making all notes, revise them. I sometimes like using quizlet and sometimes flash cards.
4. Do a ton of past papers and see which areas you are still unsure about. Then repeat.
For the more subjective subjects such as English, where the marks can vary according to the marker, I'd recommend a different method. Start by creating a format, or a structure that will guarantee a high mark. For example, you need to know how much you need to write per paragraph, how many points to include, what quotes you may use etc. Then do practice papers in timed conditions, as you need to get use to the time pressure as soon as possible (many of my friends didn't perform as well due to spending too much time on certain sections). Make sure to give all your past papers to your English teacher to mark for feedback.
It is important in GCSE to
not be stressed about exams too early. I started serious revision 1 and a half months before the first exam, and only did light revision the month before that. Don't do it about a year before, as you are likely to lose the motivation to revise and thus, will affect your grades.
Bare in mind that the language subjects are a bit harder, especially because you have to start a long time before the other subjects. This is because language GCSEs require a lot of memorisation of vocab, which is certainly not possible to achieve a week before an exam. The best way of revising for this imo, is to use flash cards or quizlet (language on one side, English on the others)
I wish the new year 11s the best of luck in their GCSEs
