84: "redundant makes a better learning!!" -Professor Jin
Professor Jin is my professor for EE 306, the first Semiconductors class, and she has some funny mannerisms. English isn't her first language, and I want to be very clear that I am by no means mocking her, I have been enjoying her class, she's a decent professor, and she's a very nice person, her accent and grammatical decisions simply bring me joy for their novelty.
I forget exactly what she was referring to in this case, but it was funny enough that I wrote it down. She is also right, doing things over and over again is one of the best ways to learn.
