I love Mr. Bourdon, but I am a strong math person (probably a math major). Also, I took previous calculus courses. He is extremely passionate about teaching, and definitely makes you think to uncover the answer. However, I can easily see that if you hadn't taken calculus before or aren't the strongest math person, that his teaching style can be confusing. His office hours are rather empty, I strongly recommend attending them. Put in the work and you'll be fine!
