How to use it
Practise like it's the real round.
1
Read the tables first
Tap a table to see its columns and a few rows. Interviewers expect you to ask about the data before you write.
2
Type it yourself
No copy-paste. Run often. Read the error, fix it, run again. That's the actual skill.

One a day
Keep the streak. 30 questions in 30 days covers what most analyst SQL rounds test.
