cmiyun6877's honest review, The Essence of SQLD: Mastering the Yellow Book Problem Set course

Thanks to you, I passed on my first try even though I knew nothing about computers! The "yellow book" was so difficult that I wanted to give up, but thanks to you, I was able to finish it. On my second pass, I tried to solve the problems on my own and re-watched the lectures whenever I got stuck, which helped me find many familiar problems during the actual exam. Thank you so, so much.
