I've taken a few classes with Ms. Riggers. I don't really like her teaching style but there are critical skills to learn from her classes - especially if you wanna go into business/finance/marketing. She has a lot of 'pop quizzes' but they're not hard at all. They all seem to be common sense or applications to the readings she assigns, so do them. There's lots of homework and papers though, but she does prepare well enough for final projects.
