Did mine down @ Cabair Bournemouth and finished up with a 95% average. Bloody hard work but I found the 3 sittings really suited me and the instructors were great. Make sure you choose what suits you because the ATPL's are a tough 6 months so you need as much as possible going your way.
Good Luck whatever you choose. Get your head down, work your arse off and they'll actually go quicker than you may think.
