your videos saved me. I was so overwhelmed in my class and was almost ready to give up and try again next semester. Your teaching is so good and I am doing better. I took an online class and do not have a car to get to the Math Lab for help. I was able to find your series of videos and there are perfect for my Math for Electronics and Computers. Thank You for the time you spent to help students like me.

This method is very easy to me, eventhough I get confused by the other methods. what does that say about me?
