I actually took a leave of absence from my part-time job. It was just too hectic to try and work and student teach at the same time. At least at first it was...I had two student teaching assignments, each 9 weeks long. Definitely during the first 9 weeks I'm GLAD I had the time off. But the only reason I would have been able to work a little bit in my last 9 weeks, is because that master teacher didn't expect as much as the first one did. So I had a little more time to work with...I guess it just depends on the teacher and the workload. If anything, weekends would be best!
