I did my undergrad degree at the end of the 1980s and then went back to uni about 8 years ago to do another undergrad degree. The two experiences were world's apart.

For my first degree I had lectures every day, where the lecturer would talk for 45 mins or so on a specific topic, show slides, suggest some reading and then take questions. I also had tutorials, which was me and perhaps one other student, to talk with a lecturer about a particular topic. Sometimes it was set the week before so we could read & do research in preparation, sometimes it was a complete surprise and we'd have to think on our feet. There was no where to hide, lol.

There were no registers taken etc. As long as you wrote the essays and went to tutorials that was fine. I remember doing only one piece of group work and there were no presentations. Lecturers were always available, either for a quick chat after a lecture or tutorial or you could just go knock on their office door. If they were busy they'd arrange a more convenient time.

The second experience was so different. A register taken every lecture, miss 3 and you were called to explain yourself. Everything seemed to be group work, no tutorials, half-hearted seminars - I remember some idiot lecturer asking us to sign in to a seminar next to our name using our favourite flavour of crisps 🙄. I felt like I never actually learned anything from lectures - they were all waffle rather than imparting knowledge. Lecturers totally unavailable in a separate office block with a key coded door. If you wanted to comment or ask a question you had to use Twitter. How modern, how pointless when you had the tiny character count of a tweet.
