I recently purchased a paid course, studied for a while, and suddenly when I logged into the website, it wouldn't authorize me. I logged in and saw a message: "It seems that your subscription period on the site has expired! You can buy or renew your subscription here." I was in shock because when I chose the course, there was a field for "Subscription on the site," but I didn't understand what that meant and bought a one-week subscription. I wonder if anyone could master the basics of PHP, SQL, and OOP, and then create a website in just a week? It seems impossible to me. In the end, I was left without the course and without money, and I don't know what to do. The quality of teaching leaves much to be desired; in some moments, the explanations are so fast that you can't grasp anything. During the SQL lesson, when we needed to create a website, I spent half an hour and managed to cut the code in half.
