how difficult are the classes? is it feasible to have a job as a full time student?

<p>i have to take 15 hours to maintain my scholarship, but i want to get a job to pay for my rent so my parents don't have to. are the classes so difficult that a part time job (<20 hrs/week) would adversely affect my grades? i'm going to be a freshmen, and i'm just worried that i won't be able to keep a decent gpa. i hope to get into vet school so that's pretty important...</p>
