How hard is it to maintain a good gpa?

<p>hey guys,
I really truly appreciate all the help so far. I’m planning on spending most of my time in the library or in my time studying if I’m not in class or eating. to get away from the books I will probably workout for 35-50 minutes a day by running or possibly playing intramural sports if they DO NOT get in my way of studying. I plan on getting at least a 3.6 gpa and I hope its possible because I really was lazy throughout high school and got a 3.4 high school gpa and 3.3 science gpa (I never studied freshmen or sophmore year for science but when i studied for ap bio I got a 4.0 and had one of the toughest teachers in the area). I really will work my bottom off, I just want to know if its possible even with the weed out courses because frankly my older siblings were finance majors at PSU and NYU so they really didn’t deal with the tough science classes.</p>
