feb gcse revision

I would honestly really recommend past papers.They're so important to make sure you know the exam structure and timings as well as spotting your strengths/weaknesses as you said.
I would also say breaking down your subjects into small topics and blurting everything you can remember about that topic onto a whiteboard or piece of paper and then adding in anything you've missed with a different coloured pen. Active recall techniques like this are really important for remembering knowledge, which is why l'd also recommend using flashcards and testing yourself on them regularly.
Everyone revises differently and what works for one person might not work for you, it's all about finding the methods that you find most effective. It’s also never too late to start revising just try not to cram and make sure it’s spread out over time as it’ll be much more effective. I hope I've helped you in some way

thank you so much for the help!! I’ll definitely be trying those methods. Also, do you know how much time I should be spending per day revising to avoid getting burnt out + any useful websites/apps that you like to use?
