Key Stage 2
You don't need any books or equipment for this level, I'll provide all you need. But if you have something you want to bring along, that's fine.
Homework will be varied, and often comprises playing games (or so you think).
Key Stage 3
You don't need any books, but if you would like to have one, have a look at the recommendations for maths and science on the books page. You'll need a calculator for some topics. You can borrow one of mine, but it's better to get to know your own. I can recommend suitable models, and they're not expensive.
Homework will be fun examples (where I can make them fun) of the skills we've learned in the lesson.
Key Stage 4
If your teacher recommends a revision guide, bring that. Otherwise we can use one of mine. I have some recommendations in the books page. Check the appropriate sections for maths and the three sciences. You will need to bring your calculator with you so that you can get to know some of the weirder keys.
Homework will be practice, sample questions and past papers when we get close to the exams.
A Level
Bring your class text book with you, so that we can go through the examples and questions together. A-level problems are not ones that can be made up on the fly! You will need to bring your calculator to every session and we'll look at how to use it in different modes.
I don't set specific homework for A-level students. Firstly you have enough already. Secondly you're mature enough to realise what you need to practice. I'll recommend questions from your text book that I think would be helpful for you.
