I'm not sure if this kind of post is appropriate or unwanted, but I'm feeling kind of desperate...
I feel how I've been studying has been unproductive. Poor test scores and lack of understanding of my core sciences. Has anyone found a method of studying that seems to work well?
Find out what works best for you. Personally, I learn best from having someone teach me and then having me teach someone else. It may sound weird, but just repeating everything in my own words in a way that allows someone else to understand helps.
Also, if I already have a little bit of background before I learn it then I retain a lot more. If the professor publishes the notes before lecture, I run over them quickly to get a picture of where the lecture will go and to get a brief intro. Then in lecture I just sit back and listen. I don't take notes because I find myself becoming fixated on the little details instead of the big picture. I will occasionally jot something down, but my main focus is the listen and learn.
At home, I go over the notes one more time. This time I see if anything doesn't make sense and learn what doesn't.
This entire process doesn't take much time because I just focus on learning the most during lecture. It is only college, so I don't study hardcore until right before tests.
I have a calendar printed of the entire semester and when everything is due/when tests happen. I make sure I spend my weekends preparing for the following week. It really doesn't take much effort, just time management and finding which study method works for you.
