I've had this professor twice now, and I really like her, but she has a problem with going several minutes past the end of class. Sometimes it's with actual content she wanted to fit into the day, and sometimes it's not content related. It's gotten pretty frustrating because in theory, I should have plenty of time to get to my next class, but when around half of my ten minutes are being taken up, I end up running late most days. I thought it may improve with time because she's a very new professor, but it's gotten worse over time. It's a very small class, so it's not like a giant lecture where I can dart out a few minutes early and not be noticed.

Is there any way to politely address that I need to leave at the time the class is scheduled to end? I feel like it's hard to slice it in a way that doesn't sound rude, but I'm really really tired of being late to my second class.
