Can I still get A’s if I start revising now? Watch
GCSE's and university - yes.
A Levels - probably not.
I don't see why not. As long as you use revision techniques that suit you to get the most out of your revision sessions. Don't do what I did when I did my GCSE's in 2015 and stay up till 1 am and then wake up at 5 am and start revising again in the weeks leading up to your exams. Make midmaps of all of your subjects and make flashcards and get your friends and families to quiz you on the subject.
