I can tell you my experience. I was placed in a gifted program in the 4th grade, iirc. From day to day we would skip a different class and attend the gifted program instead. One day I failed to turn in an assignment for a one if my "regular" classes. I didn't know about the assignment because I wasn't in class the previous day. The teacher told me that I should have been able to keep up because I was in the gifted program. I hated every minuted of it and ended up dropping out in fairly short order. Although I'll admit in retrospect that the program certainly could have been run better.
