Would take again

I absolutely LOVED Flenner! He does lecture for the full 3 hours however it wasn't too bad for a class that was 2 days a week. He went in-depth on the content and made it very easy to learn. Attendance was not required however if you miss a class you will miss a lot of content! Overall an amazing Professor, definitely recommend him!
