My basic advice to you for English is: If your doing an essay in the exam --> DON'T DO THE ESSAY ON THE SPOT!! Have a Preplanned essay that you've memorized, done a few times, asked the teacher about etc. Make sure you answer the question though, so you might need to improvise
For Legal Studies: READ THE TEXTBOOK AND WRITE OUT NOTES. This is the best way I find to learn. I read textbook then right out heaps of notes on it. But make them notes that you will remember. Not heaps of notes, not a lot. Maybe a few sentences, a few definitions here and there etc.
It seems to me that your strength lies in maths and the sciences - not the written and spoken word. Maybe you might want to spend more time working on the subjects you are weaker at.
All the best
