ATPL books

[Tommymoro7]

Hello everyone, I'm working on the ground part of the ATPL, but I'm finding some difficulty with the books. I have both Oxford books in PDF version and padpilot, but I often find them too scattered. Is there any more "concise" book or summary that has all the necessary information to pass the exams?
