One of the best statistics professors I have ever met who has a very clear structure in teaching, which makes you understand the materials very well in a short time. And he is very approachable who reply to the Email quickly in details. The materials in this class is extremely easy. You are extremely likely to get an A or even A+ as long as you listen to the lecture carefully and do the homework problems. You also need to understand the example in-class which is really help for the exam. The grading of this course based on 40% of quiz (you can do very well as long as you pay attention to the lecture, and there is also 5 drops for the quiz) and 60% of exam ( there are two exams and 30% for each, you can also do well as you understanding the in-class example and homework). I really like the way he teach the class, and the workload is relatively low. Please choose Professor Weinstock if you have chances.
