Depends on your previous experience.
As an ex FE I found some of the Mod 1 subjects 'challenging' but Mod 2 not so bad so far (but I have covered some of these subjects before)
That said it didn't stop me passing all the first 8 at first attempt and if you do the coursework, listen in to the lectures (and work hard at night) and most importantly of all, study the feedback till you go crosseyed you should have no problems.
Remember put in the study and you should do fine...
