 Honestly, I felt so locked in in this class. Like, I felt like I really understood what was going on. Like, I understood the points that were being laid down in the lecture. When you think about it, it's not surprising. When you're concentrating on one thing, like listening to your professor, it's easier to focus than when you're trying to take notes, search for next quarter's classes, and play connections all at the same time. But don't just take my word for it. Jim Roberts at Baylor University says so too.
