You probably wont need ground school so to speak. Perhaps the odd explanation here or there from your instructor.
Get cracking with the books while you have some time and dont do what I did and let the flying catch up with me and try doing a whole book in a night because I was likely to go solo the next day or something silly.
Get the PPL Confuser book BUT dont use it until you have read the text books, otherwise you arent really learning anything but answers.
Read a chapter, do the practise questions in the back of the book, repeat.
Then once you have finished the book go through the confuser and set yourself some mock exams.
