Striking the right balance

Remember, our motto is "learn by doing"! Although our courses follow a "what-why-how" structure, we want learners to gain knowledge through practical examples and experimenting with code as much as possible. Although a few courses maybe be conceptual in nature, most of our courses focus on coding.

Let's say you will be developing the course "Joining Data in SQL" which will cover inner, outer, and left joins as well as self joins, semi joins, anti joins and cross joins. What is the ideal ratio of exercise types you should aim for?
