Helping my brother

My mum has asked if I would help my brother revise for his exams, as a kind of personal tutor. She is going to pay me for my time so I want to do it correctly.
Has anyone got any tips on how I should go about this?

I found it best to get a copy of the syllabusses and go through the topics by working on lots of past questions, spending more time on the areas they found difficult. I met up with them a couple of times a week and emailed at other times.
I only did science and maths subjects though.
