<p>There were labs at my school that were until 11 o’clock at night on Fridays. It was all freshmen who were stuck in those. It happens.</p>
<p>Anyways, if you’re worried about evening classes, I would definitely call the departments and see if there is any way you can get an override into an earlier class. I would also constantly be checking for class openings. If there is an Add/Drop day at your school (the last day to add or drop a class, usually in the first week of classes), I would look on that day for openings and if there’s a final day that tuition has to be paid for or else classes get dropped, I’d look that day.</p>
<p>Your calculus class is probably doable, but that Chemistry class might really suck for you. Definitely check with the Math and Chemistry departments and see if there’s any way to get an override.</p>
