Studying strategies? o_O

One of my studying strategies is being alone in my room and looking over my study guides or cheat sheets. I don't really like studying in groups or anything like that. I feel distracted and like i won't get anything done. I study quietly, it's weird how I don't study out loud. I study or look over each study guide for about 30 minutes or so. I try not to rush myself while I look over them cause then I'll get overwhelmed and frustrated. Or I'll just look over one study guide one day and then another one the next day. It works for me because I'm by myself and I'm more organized with my study guides.
