Should I Take The Job?! Please Answer/Help?

So, it's my second year of college, while I have had one other job in my lifetime...I had it during a summer when there was no school. I'm great at working, if anything I'm a workaholic. I'm not worried about doing well for a job, BUT there is a job opening at my college for a conductor...all of our students drive a campus run bus service...and a conductor helps on the double Decker's would just have to memorize routes, ring a bell for stops, memorize stops, and hold a flag for speed bumps or caution(when people get off). It seems simple and I have a friend who does it. The schedule is crazily flexible, and the job would give me about 8.50 an hour. I know it sounds great, and I would meet lots of people, and make lots of friends and have some income. But should I take it if I feel it might exhaust me to the point my cles won't get the attention they need...my load isn't that large, but it is rigorous this quarter none the less. I just want to make sure I don't fail because of a job, and at the same time I want the job for the fun, income, and knowledge...not to mention I could work with this guy I like...but that's not the reason for the job...a friend actually suggested it, because it works well for him and they are hiring. What do you think? Would you take the job? Is it terribly hard to work part time while in college? Thank you!
