📢 [Course Update Notice] Upgraded in November 2025. (Last Updated: November 27, 2025)
Update Details
- Changed practice platform from w3school to solvesql for faster and more stable SQL practice
- Updated and added existing SQL practice problems (total of 20 practice problems for intermediate level)
- Provided new SQL cheat sheet
There are many SQL theory lectures, but why aren't there any courses that can help you build real skills by combining them with problem-solving practice?
Just as studying English grammar endlessly won't improve your conversational skills without actual practice,
you can't properly use SQL by only studying grammar.
For those who want to immediately apply SQL in their work and for those preparing for SQL coding tests, this is a helpful course.
If you complete both the SQL beginner and intermediate courses, you'll have the skills to easily solve problems at the level of Programmers' SQL High Score Kit.
