I actually deleted that post 30 seconds after putting it up. It was a bit harsh. You must cut and pasted it the second it went live.
Back to the point. This subject has been done to death on pprune, airlinepilotcentral etc. Most EU training providers offer guidance on what exactly you need to do and when you need to do it.
Remarks like "will it be about the same difficulty as FAA ATP" makes me think you have done little research into the matter as EASA ATPL theory is long and expensive (and mostly pointless).
So sorry for having a shot at you (I did take it straight down) and if you have any detailed questions put them up.
