I think that CRS is a great place if you want to learn. The teachers treat everyone some. They might not be the best in some subjects but they try there hardest to learn new things for the students. sense there are not a large amount of students the teachers have time to help everyone. The teachers will stop at nothing to help you if you do not get something. They deal with things like bullying as soon as they know it is happening, although there is not much if at all bullying going on most of the time.
