One of best teachers 'I've ever had. Not just in Calculus but overall.
Bergen is a true star, well anyone should be after 30 years! No teacher has students get as many 5s on APs as he does. Calculus is not easy, and few schools offer the BC course, which he does with great success. One of the best teachers I've ever had, sad to see him go.
I don't understand the poor ratings here. Mr. Bergen is one of the best teachers I've ever had. That includes the first year of college
