Since I didn't have the opportunity to consult a personal teacher, I started looking for interactive learning resources on the Internet. And then I came across the SQL Academy platform. I was immediately attracted to the fact that this resource is 95% free. But the main thing is the quality of the learning material itself. The material on SQL Academy is written in an accessible and simple language, understandable even to those who have never written SQL queries before. There are a huge number of examples and a reference for additional self-education. But the most important thing is the interactive platform for writing queries, where you can immediately apply the knowledge gained.

Before I was recommended the SQL-academy course and trainer, I thought SQL was something overly complicated. But no, in the SQL-academy course everything is explained in detail and in order about all the necessary operators and functions of the language! Moreover, there is an excellent trainer with a bunch of tasks of varying difficulty levels, a reference with everything you need, and even a sandbox! In general, thanks to the guys for such a contribution, especially since you can complete the course and trainer absolutely for free!

Just a great interactive textbook to refresh or learn the basics of SQL. I will definitely continue learning and practicing on this platform.
Liza
The site is great!! I came across an article on VC, decided to try it, it works great, the tasks are interesting, the UX is at a high level! Verification is based on the result of the query, not the query itself, as it is on many sites.
Nikolay
Excellent presentation of the material! I was very pleased with the presence of tasks from interviews of large IT companies.
