Wouldn't take again

Dr. Doub is super passionate about what shes teaching but it was a difficult class. Theres tons of online homework thats due right before each exam (theres 3), along with written word proble projects. The final is almost all multiple choice which was nice. Definitely have to do all the work and teach yourself sometimes. Textbook is helpful.

Skip class? You won't pass.
