I am taking linear algebra class at my own college. It's a top 20 university, but the professor totally messes stuff up! He didn't even emphasize the closure of linear combination when he introduced vector space! I thought linear algebra is super hard but I realized it's actually not after I watched this video!####[['professor', 'Instructor', 'NEG'], ['linear algebra class', 'Course_General_Feedback', 'NEG'], ['video', 'Teaching_Setup', 'POS']]
