Trying to rewrite my paragraph. Wanted to say "This class has been a challenge, but very self gratifying to me."

Question

Is there another word beside gratifying I could use?

Answer 1

Remove "self" -- "to me" takes care of the idea.

Answer 2

I just saw where you helped me below. I left a question on the comment earlier.

Thank You, Thank You

Answer 3

You're very welcome!
