Deepingsauce's class that I trust and listen to... I waited a long time for the next class after taking the quant class, and as expected, this lecture did not disappoint. I have taken many online lectures, but this is the first lecture where I didn't have to look up the parts I didn't understand while listening to the lecture, and it was all resolved through the lecture video. It was a good money. I look forward to the follow-up lecture.
