One of the best CEE classes you can take if you are on the structures route. Professor Bondy is an expert in PT concrete and explains concepts very well. He is super helpful and even offers to check your homework and project calcs the Sunday before the due date. Class is asynchronous and all videos are posted ahead of time. The only thing that is in-person are discussions. If you go to discussions and the lecture before each midterm, Professor Bondy often gives hints on what's on the exam so there's really no suprises when you are tested. It is pretty clear that you also have a competitive edge on your classmates who don't take this class bc PT is widely used in industry. Concepts weren't too hard if you follow the videos and go to discussion.
