Difficulty remembering things from class

<p>I have difficulty remembering things after a class. Usually I forgot what I learned from classes three years ago or a semester ago. That's why I'm not smart. Because I forget material I learned from long ago. The longest things I can remember are from like three weeks ago. Three years is pushing it.</p>

<p>I need help remembering things and improving my memory especially since I'm majoring in accounting. I need to change my study habits for college.</p>

<p>Do I have a LD or something?</p>

<p>Also I make stupid mistakes in Calculus, Physics, and Accounting. Maybe I'm dyslexic? I ocassionaly mix up numbers and therefore I get marked down for math because I forget details. What should I do?</p>
