I have taken his 6B and 117. All his exams are difficult. When I was in the 6B, he only gave us the PDF instead of videos. He recorded videos while teaching 117. Although his average score on the exam was very low, he said he would not curve. There is a lot of sarcasin his email. This is a very mean behavior for students. Don't choose his class!
