Studying for the ATPL (or anything else for that matter) is a bit like having sex............If you're finding that it's a pain in the Ar*** then you're doing it wrong.
I meet a good many students who start the course by saying "I can't do maths". My response is quite simple....If you keep telling yourself that then it will be true. But if you keep telling yourself that you are going to become better at maths, then you will probably succeeed.
If you tell yourself that the ATPL material is a lot of "pointless, tedious sh*te" then you will never enjoy the course. This will make the whole thing much more difficult.
But if you start with the atitude that you intend to enjoy learning something new, then you will find the whole thing much easier and at the end of it all you just may find that you have enjoyed it.
