No, I would continue studying solidly through to November. Last year, when I took my own GCSE's, I took maths early right at the end of October and I have to say that I studied not too much even though I knew it was coming which meant I panicked more (not particularly because I was going to do bad, I got an A*) so actually partially for your peace of mind more than anything, I would advise just continuing studying though maybe slow down a little just whilst you go back to school and get busy again. But study hard over October half-term,
