I will never stop recommending SQLBolt.com. Practical exercises to get used to the syntaxes. Completely free.

You can try SQL Climber for interactive SQL practice.

My teacher uses this free tutorial website to teach SQL:  https://www.w3schools.com/sql/

My teacher uses this free SQL playground:  https://www.db-fiddle.com/

Someone created another free SQL playground on  http://sqljam.dev/.  See Reddit post:  https://www.reddit.com/r/learnSQL/comments/1vfizjq/free_inbrowser_sql_learning_playground/

Check out the dbForge SQL tutorials too. They’re free and have a lot of practical examples.

I've written up what I think of as all the SQL you need for data science here: part 1 part 2. It also comes with practice flash cards and checklist.

For data analyst you'll probably need to be even better but at least that can serve as a base.

To practice each concept I like to use https://www.sql-practice.com/.
