<p>last spring i had a full load of classes...</p>
<p>then summer...i took gen chem and differential equations because i switched majors and i didnt want to be "behind"</p>
<p>now i am in organic chemistry 1 , calculus, physics 1, physics lab, swimming</p>
<p>i am not studying the same way i used too...i feel tired all the time...when i am studying i cant concentrate</p>
<p>i have a 3.8 gpa... and my b's are from non science related classes (i made a b+ in history)
so its not my work ethic or even time management...because ive been doing fine
this is my third year at university.</p>
<p>how can i restore myself to 100%? any advice?</p>
