job interviews help!

Ka

So I just recently moved and I have a job interview tomorrow for a full time position, but it's almost certain that I will get the job. I also have another interview on Tuesday for a part time. The part time pays a bit more but that doesn't matter, also the part time is more relevant to the degree I'm working on. And on top of that I am also a full time college student. Would it be best to accept the full time job or interview for both and if so how do I tell them that I have another interview somewhere else without risking my chances of getting the job?
