You are doing the AQA GCSE Physics course. The home page for the exam board is here. Always make sure you are on the from 2016 specification.
Because this is a new specification it can be difficult to find past paper questions to do. However, most of the questions from the old specification will still be useful. The ones that you have to watch for are the Energy section. Also there are some bits that are no longer on the spec so if you are doing old questions, don't panic if you come across things you can't do. If in doubt, ask.. All the other exam boards now have very similar specifications so their websites are also worth a look.
This is your GCSE. Take responsibility for your progress. Help will always be given if you ask for it, but only if you have tried to solve your problems first.
There is now so many ways to get information that it is pointless spending lesson time transferring information from me to you.
There are much better things to spend lesson time doing.
