Take this class if you are interested in math. Professor Greene is an excellent instructor for this honor-level course. He is great at explaining difficult topics, and he gives a lot of examples and intuition behind those abstract concepts. The professor teaches a lot more than what's in the standard Math 115A class. Some homework problems might be challenging, but the professor and the TA are pretty helpful in answering questions. Many problems on the midterms and final are already discussed in class. The final consisted of 11 proof-based problems, which was terribly long and took 15+ hours to complete, but this will probably be different if this class is offered on-campus after the Covid-19 period. Overall, this class is suitable for those who love math or those who want to study deeper in linear algebra.
