It is easy for cs students like me. For those who are in biology... I am not sure how you feel. The course is a quite useful intro course for people who want to do research in bioinformatics.

Don't take this class unless you have previous algorithms, statitstics and biology courses. She doesn't explain the algorithms well enough to understand and examples in the slides are not present. If you ask a question, prepare to get into an argument with her about why you don't understand. Midterm is also very difficult, not enough time.
