Then, real interview questions
A new challenge every day, for everyone, from real SQL interviews, in collaboration with StrataScratch. The Challenge library keeps past challenges at three levels.
Before you start
I'm not technical. Can I really do this?
Yes. Lesson 1 starts at zero: nothing to install, nothing to know first. Most people write their first real query in about five minutes.
Can I really learn SQL on my phone?
That's the whole idea. Lessons take about five minutes, you build queries by tapping or typing, and every query runs so you see what it does. Waiting for the bus counts.
What if I get stuck?
Ask the AI tutor. It explains the idea in plain words and nudges you toward the answer instead of just handing it over.
Is it free?
Modules 1–3 are free forever. No ads, no hearts, no energy bar. Premium unlocks the rest of the course, the Challenge library and unlimited tutor help: $9.99 a month or $79 a year.
Which SQL will I learn?
PostgreSQL, from your first SELECT to window functions. Moving to MySQL, SQL Server or BigQuery later is mostly small syntax differences. Already know some? Take the placement test and skip ahead.
Will it help with interviews?
Yes. There's a new interview-style question every day, from real interviews, in collaboration with StrataScratch.
