I listened to all the advanced problem-solving before the SQL coding test. It was good to solve the problems I solved in the intermediate problem-solving in a new way. If I had to solve the SQL problems on my own, I wouldn't have been able to solve them this far. Thank you for the great lecture. +) Thanks to you, I got a perfect score on the coding test. The interview is the problem, but I feel really good about getting a perfect score on the coding test. Thank you.
