If its your first time taking the class and you want a relaxing fun class, take it for credit/no credit. If you want the grade and its your first time, you HAVE to practice and know the dances, songs, drumming well. At least well enough that you stand out in class. If you don't stand out to the professor, you're not getting an A. She tends to pick favorites, which you'll catch on fast. It's no easy A class but not too difficult. She's really nice in person but through email she can be blunt and scary.
