English exams are the worst for me because I am 100% orientated towards Maths... I got DD in my English mocks but A* in my Maths...
so I'm probably not the best source.
Anyhow, my revision timetable consists of lots of English, slightly more literature because I actually enjoy learning it myself!
What I am doing is reading every chapter (I am also doing OMAM) and then making notes on important quotes from my class work notes and online. There are some fantastic sites such as:

I am also making key contextual points (for OMAM it's events like the depression - dust bowls, wall street crash, worker migration), key themes and making lots of notes on characters because they appear every year.
The issue with literature is that they can literally ask any question and if you haven't covered that then you're screwed... however, looking at past papers and seeing which questions they have already asked can give you a BRIEF idea of what they are going to ask.
With Maths it is just practice, practice and practice. Covering an area once will not suffice your ability to apply this in the exam. You need to find lots of examples online and do them, no matter how hard they are (with in GCSEs obviously). Once you think you have grasped it, find ALL past paper questions relating to that area of topic. This seemed to work for my statistics which i got an A in last year and an A* in my Maths mock.
Another point to mention with Maths is that you tend to revise topics you feel comfortable with. It's very tempting to do this so make of a list of everything you're not sure about and then only revise those. So if you still have your Maths mock or any recent Maths papers, go through them all see which topics you didn't get many marks on. No point revising trigonometry if you can answer questions confidently, it's just a waste of time.
And after you've revised all your topics, do lots and lots of past papers!
