As a teacher, I feel this is wrong. A lot of students fail by trying too hard to understand.

They listen in class, then read the text and notes you posted, then watch a Youtube explaination, then ask Chat, then ask you questions ... anything to avoid trying to do a few practice questions where they might make a mistake.

It's like watching people try to learn to play basketball when they are afraid of shooting hoops in case they miss a shot. So they watch videos or read books to really understand how to shoot hoops. And then fail miserably when they are tested.

OK, you could argue that exercises build a type of understanding, and listening to explanations builds a different type of understanding, and the former is more useful, but people don't understand that.
