Say, for example, I’m taking a Mathematical Proofs course (MAT102) but due to personal learning ability I wish to switch to a different lecture (i.e. LEC0102 to LEC0103). The time schedule and the material is the exact same in both lectures, the only difference is the room. Even though it is now too late to transfer to a different lecture, what would be the repercussions of me skipping my scheduled lecture and attending the other one instead?
If by repercussions you mean scary official university people who are going to track you down and punish you for your HEINOUS LECTURE SKIPPING, you’re probably not going to encounter that. Let’s be real, in big lectures, it’s fairly easy to slip out of one and into another. But is it a good idea?
At the end of the day, there are always going to be little differences between one prof and another, and your prof is the one who administers your tests/quizzes, so it might be a good idea to stick around in their lecture. They might emphasize different things from another professor, and when it comes to writing the tests, those things will come less easily to you than to your classmates. Also, you could miss out on important administrative information if you go to a different lecture.
If you’re really bent on going to this other lecture though, why not talk to that other prof and/or the registrar’s office about possibly switching into it? Your case is pretty specific and they might be able to accommodate you. Who knows? I’d say it’s worth giving a shot.
Hope you enjoy your class, compadre, whatever you decide.
