Revision

I'm currently Yr 10 and I'm worried about when and how much I should study each week. I do quite a lot of out of school sport clubs on Tuesday,Thursday and Saturday and I struggle trying to study or do homework on those days but overall how much should I study per week?

Everyone is different, depends really how are you doing in class. If you are fine and already ahead then you don't need to worry, if you are behind and the teacher sounds like they are speaking a foreign language then you need to spend sometime every night or a bit on Sunday. It really depends do you feel behind and how well you think you absorb information after lessons. Personally I think early into year 1 you still have time but a little bit is still better than nothing.
