I'd be weary of taking on any form of study for EASA exams if your not going to be getting hands. I'm currently half way through a full time course which if everything goes to plan will give me all my B2 exams but from experiance and from people who've finished my courses experiance companys are very reluctent to take you on because you just don't have the knowledge that goes with practicle experiance.

However you need 400hrs work experiance make sure any hours that you do can go toward these hours.
