Not too easy. Not too difficult.
It's very very thorough in its teachings of biology and it covers plenty of material along with lots of practical applications of biological techniques in the lab. The labs are also pretty fun and interesting, if a little gross at times (etherized gnats *shudder*).
Easily the most fun part of the course was the clicker questions during lecture. They make everything fun and they make sure you have your thought process correct going into the tests and etc. And, depending on the day, they're pretty fun.

Advice for students:
Take notes and read the book. Lots of the test questions are incredibly specific and not as general as some of the clicker questions might lead you to believe. Pay attention to experiments and the people who did them. And when it comes to the lab reports, be thorough and overexplain. It might seem like it should be obvious to you and the professors, but they don't read it that way, so overexplain.
