    I've spent the last month trying to fully understand this concept by reading boring textbooks for my college course. This video did that for me in 10 minutes. Excellent! Highly recommend!

    Watched many videos but had no clarity about differences between keys, but after watching this video i am very happy that i understood them very well and even the entire normalization series is a life saver. Love you Studytonight

    I just left a lecture where the professor described all of these keys verbally, with NO examples, no visual aids, and, prior to this lecture, had never mentioned Keys to use. Everyone in class was glossy-eyed the entire lecture. THANK YOU FOR THIS!
