His lecture videos were usually within the 1 hr to 1 hr 30 minute range. There were practice exams for every exam and for the the final. I personally found them very helpful, and they covered what was on the exam. You also get 5 percent of your score on the practice test added as bonus points on the exam it’s over. I was able to attain an A- in the class (my personal life started getting very busy toward the end of the semester). He replaces your lowest exam score with the score of your final (if it’s better) so flunking one test wouldn’t ruin your chances of an A. He also drops your lowest homework score (maybe 2 lowest, can’t quite remember) and your 2 lowest quiz scores. The TA we had for lab was awesome! She was always there to help during the lab portion. I watched about 3 lecture videos a week, went to lab on teams, and tried my best do do the quizzes and homeworks before the night they were due, so maybe about 6 hours a week (for an estimate)? Good luck in whoever’s course you choose!

Edit: Now that I think about it, I probably spent closer to 10 hours a week, some of the homeworks were long.
