I've had Alexander for 3 classes and all of them were amazing, great teacher and even better friend/almost parent figure. Truly cares about his students and is a very understanding guy. Talks about his life and shares stories but always very interesting! He is a very smart guy and I have never met someone who dislikes him as a person or as a teacher. Memorization is required for his tests, the short answer parts are easy to get good marks on but in some classes the multiple choice can be very hard and random, still so easy to finish with a high 90 as there's lots of assignments you can get done in class time. I never didn't get an 100 on an assignment in his class as it is very easy to read the textbook and find the answers.
