I'm bad at studying. I usually read the posts on the discussion board first and then get less study time in.
When I studied Statistics I had to take my laptop into a room away from anyone including my wife. Someone asking me a question or just making a statement to me can totally derail me. The discussion board has really benefited me though. I believe it has shortened my study prep material by getting peoples suggestions.
One thing I heard works is having peppermint candles burning while studying. I got a little heater thing from AVON from my wife that you put a few drops of scented oil in and it will slowly vaporize it with the mint smell. I really think it helps.
I listen to no music while studying and I don't listen to too much music anymore in general. I get dumb lyrics stuck in my head the whole day and can't concentrate. I really value silence and I enjoy meditating on the deeper things in life. So no music unless it is classical.
I can't study with people around at all. I am quite social and I usually end up talking. I can't concentrate when others are talking around me. I feel for those in a baracks. I've been there.
