RevisionWatch this thread
You should DEFINITELY start revising when you start Year 10. No doubt about it.
Different methods of revision work better for some people than others. Search some up on google or Youtube and have a go at each - see what works for you. I personally find that decorating my notes helps me get a lot more invested into my work, that's how I got 9s in both my English exam sections! I was predicted 4s until I began using this method!
Once you find a suitable and efficient revision method, create a timetable that you can rely on and most importantly: stick to. This will help you get into the groove and will help you motivate yourself each time you want to study. If you let your parents know you're going to study at these times, they will leave you alone so you can get more done, which is just a little added bonus.
As for how long you should do this, at this stage I would maybe aim to do around an hour to 45 minutes worth of revision on some select days, not every day - you need to have a life. On any subject you like for now. however when it gets to be around the time that you have to start doing your mocks, I would up this to about an hour to an hour and a half per each day you decide to study, on the subject that your next mock is on. If you have 2 mocks on the same day - 45 minutes each, 3 mocks - 30 mins each and etc. When you get to Year 11, I would personally up this again, but it's your choice.
just a bit of personal advice more than general here - don't let anyone other than your friends and your teachers know you're studying. There's a lot of nasty people (likely to be the chavs) who will call you names like 'teacher's pet' and 'neek' or whatever. Keep your studying to yourself to avoid all of that. If it does get out, ignore it. They'll be the ones who come out with 2s and 3s on results day whilst you're there with your 7s, 8s and 9s. Trust me, I've been in this EXACT position on my results day a few days ago.
Overall don't let studying take over your life. Make sure not to forget to ENJOY Years 10 and 11, they are your final years until you start looking for higher education! Go to those parties, meals and sleepovers. Live out your teenage life to the fullest whilst you still have the chance.
Hope this helped
