  1. The name is not clear: SQL Habit

Yeah, that's bummer and I'm working on a better copy atm.

The course is only partly about SQL. It's more about the habit of making data driven/informed decisions in product and marketing.

  1. What one will learn from the course?

Totally missed that point. A big learning for me!

Working a new copy to explain that one will learn about how data is collected and stored in web and mobile apps, what metrics exist in product and marketing, how to measure them and finally – advanced SQL to work with data.

  1. What level the course teaches?

So glad IH community helped me with this one!

The course starts at 0 knowledge about data or SQL and ends in the very very advanced. Thinking about the new copy atm.

  1. People started typing SQL in the text input of the exercise result.

That's a very interesting design issue! Added a detailed explainer on how to use SQL editor on the website + planned a couple of lessons on what happens when one runs SQL query.


September: 40 / 220 lessons are published
October: 117 / 240 lessons are published

Planning to finish the course in the late November.


  • I've lowered the prices by 40% and will keep an early bird sale till the moment I finish the course.

  • Working on the email flow atm – I'll include a welcome survey to get feedback why and how people are using SQL Habit for a bigger discount.

Stay tuned and thanks a lot for help ❤️
