Such an engaging wonderful professor!

Rating: 4.0/5, difficulty: 3.0/5
He was my main lecturer and I really liked his presentations! He doesn't go too fast or slow and has a sense of humor from time to time. His lectures are easy to digest, beware some miniscule seeming phrases might be on midterms, but overall his presentations are pleasant to listen to. Tests are about 70% book questions and 30% lecture questions.
