My Projects on Analyze Data with SQL Skill Path

Hello. I have made 3 SQL projects. Their names are:

  1. Usage Funnels With Warby Parker (SQL)
  2. User Churn Codeflix
  3. Project-assignment-marketing-attribution

Link to my SQL projects: My-Projects/Projects/CodeCademy/Analyze Data with SQL Skill Path at main · J-Raunstrup/My-Projects · GitHub

Is there a more efficient way to query this data?
Do you agree with my findings?

Any feedback is much appreciated.

Kind Regards
Jens
