For number of exams per week, sometimes there are none, one or two. Two can be very common, so don't get behind! As for lab – we only had two labs first semester which were a few hours each, and 2nd semester we had 1 lab which was like 4 hours. Group work varies – but I would say im generally on campus 3-4 days a week. I live close so its not a big deal, but we have a few people who come from Baltimore, Columbia etc so it is more annoying for them.
For lectures, there are about 4 lectures per day, sometimes less (especially fridays) so its about 15 - 20 lectures a week. You can watch them in fast speed which is 25 minutes per lecture, but I usually watch in fast speed and stop constantly to take notes – so the lectures wind up taking 30 –45 mins, depends on your personal habits.
Parking situation is usually not bad. there are about 3 huge lots and they are in the middle of building a parking garage, which should be done by next august. Basically parking is not an issue, but the main lot obviously fills up fastest, so you might have to walk from the further lots. It is nice when we come for tests at 730am (oh yeah, all tests are at 730am!!) and the lots are completely empty. There are no parking permits or anything so you don't have to pay. They have public events on campus (I think theres a big auditorium?) which is why parking can be so randomly full.
Living in Baltimore- I would check the beginning of this thread bc I remember seeing that topic frequently
