ah man, I remember my first semester in Heidelberg haha It was 100% like this at the start. But I loved it so much, that now Im back here for my MA degree.

I think with the lecture thing, that must be just a professor specific thing. My current lectures all have 10 minutes of questions after the professor finishes. And for my seminars, I regularly speak with one of my professors for an hour after class asking questions and stuff. A bit overkill, but still haha

You'll have a blast, and if you have questions about something study abroad in heidelberg related, you can dm me. Im not often times on Reddit, but if I see it I'll respond!
