Preceptor Schedule and School

Hey everyone! I recently got hired at a large teaching hospital in my area and start August 8th. During my interview, the NM told me that after new-hire orientation and computer charting classes I will be doing 4-5 weeks of shadowing with a preceptor and will be working their schedule. I'm currently going to school (which they are aware of) and am worried about my school schedule interfering w/ my preceptors schedule. I am going to class Mon & Wed 5-8:50pm. I'll be working night shift, so I'm assuming my preceptor will be night shift as well. If he/she is scheduled to work M or W, what will they do? My classes end August 17th, so it will only be two weeks I won't be able to work on those days. How is this type of situation normally handeled?

Thanks!
