Just out of curiosity, I'm wondering if anybody else experiences this when taking University science and math courses: Unlike some of my peers, I usually gain nothing from lectures (there are exceptions with phenom professors). In order for me to retain information I need to make complete of everything and understand why it happens. If I can understand the logic behind what I'm doing I can then start to work out problems using relevant formulas. This would be ok, except since I can not usually see the logic behind the material immediately during the lecture I tend to get frustrated and completely zone out. This occurs when the lecture format is way too formal (abstract) or "dumbed" down (doing example problems using unexplained formulas). The consequence? a) I need to spend hours upon hours reading the textbook(s) until i have a firm understanding of the theory and then some time practicing handling problems. b) A thorough understanding of the content and high marks (provided I can devote the time) Does this happen to anyone else? Because most of my peers just get some understanding of the theory and spend the time solving problems and they seem to get by just fine. I feel like I'm at a disadvantage because of the hefty time i require. I don't know, perhaps I have an undiagnosed learning disability such as attention disorder deficit. I would really appreciate any thoughts or suggestions!
