The very best way to study is in quiet! Don't have anything making noise while you are studying; no TV, no phone, no music......just quiet. You can concentrate much, much, better. I was a teacher in high school for 13 yrs, then changed careers due to money. I also attended colleges many times, studying hard in quiet places. Good luck.
The process for studying is customizable in many ways, for example, you could focus easily with a TV on or maybe Classical music on. For me, its classical music, comfy chair, sharpened pencil, lowered lights, and some water. Cashews or Mints are proven to help support your brain focus as well ^^!
