I am currently doing a Summer Refresher Course at CAE (or SFA); and I must say everyone I've met so far is really nice and relaxed (so no rushed lessons, although this might change when the ATPL theory starts). But indeed, it is VERY expensive.. As one of the other commenters said: first of all see if you would pass your medical class 1, if you do; maybe start studying your physics, math and English (maybe do the same course I am doing right now), and participate in the selection tests. These also cost money, but they (as I've been told) are valid for 1 year after you've passed them, so you don't HAVE to start immediately (or at all); but they'll give you an idea as to whether you will be able to cope with studying the ATPL theory or not.
