How did charlie change during the book flowers for algernon

He went from being mentally handicapped, to super genius, then back to mentally handicapped.

Explanation:

His IQ was in the mental ret*rdation range until tests were done on him and he was an experiment. His IQ then became so high that he became a super genius at everything he learned.
