Perhaps call CTC and see if they will forward the books though I cant see them doing that without payment. Alternatively you buy some ATPL books from the likes of Transair. The Oxford ones cost about £650. Also Propilot and Bristol have iPad offerings which can be used instead of the books. This is handy by the way. I remember doing my groundschool and having to lug around those big books was a right pain in the arse. You could ask CTC if they will deduct the cost of the books from the course if you go ahead and purchase them yourself.
