FMSdata,
If you do a search there is a thread about BA A320 LHR rosters.
I note in another thread that you are starting an integrated course soon, and also you were making an enquiry about easyjet a LGW, without any disrespect wouldn't it be better to concentrate on getting through the course first.
It always good to get an appreciation of the hours worked, although once you start ground school you will not really have much time to think of anything else.
So I would personally just take one step at a time.
Good luck
