All I will say on this is Bristol, Bristol and Bristol wheather you do it full time at home or not.
Bristol I used between 2003 and 2005. They were amazing back then. Until you have used Bristol, you have no idea how good they are. If I had to do it all again, I would use them again at home and if you can do full time studying, great. The comforts of being at home, less cost, days off from study when you're not in the mood or something at home comes up requiring a break from it. Being able to go flying when you want. Perfect.
Bristol also have a Forum that you can use if you're there student. Why not find it and ask there for advice.
Google Bristol Ground School Forum and you will find it.
Maybe a visit down to Bristol for a look around the premises and at the material is a good idea.
good luck in your decision.
