"Trying To Make A Transition"

When I was in Milwaukee I went to school regularly but I didn't do a lot of studying throught my four years. Now because of my lack of studying in the past, now I can't seem to get the hang of sitting down and comprehending the material that I have recently learned. Before every test I sit in my drom room and review all of my notes and evrything I have that I feel can help me do better onn the upcoming test. Sometimes I study for up to five hours but the results are still disappointing especially because I know the long hours I spent reviewing. Everytime I study for hours and make a 'C' or a 'D' on a test, that makes me wonder should I even waste my time studying. On top of the bad grade I have to hear my families mouth about me not being focused enough and ot trying my hardest. That probably pisses me off more than my bad grade because I know for a fact when I've spent hours goin over my notes for the test that I have put my all into it but I never seem to get the results that I aim for. I guess that I just can't get use to studying and get a good grade. It's hard going from not studying a lot and now trying to study multiple subjects and comprehend them all and know them enough to score high on a test. I've tried several different ways to study but none of them seem to work so I guess either I know the work or I don't. I'm still going to attempt to study because I don't quit and if I still fail test then that's just life for me as I try to make this transition.
