Here is how I would prepare for paper 3 in A-Level Physics.
First I would make sure that all past paper questions are solved thoroughly and I understand every point of the mark scheme. I would put my problem solving skills to the test and ensure that I understand all the concepts behind them.
Then I would also do one final check of the entire specification and see if I have missed or not understood anything.
