Hello Dr Sun

I have a doubt about a question in sample midterm. how to solve 'use the function round_to_grade() to write a query that lists the names of the professors and the average grade they gave in their classes' this question? there is no question of this type in the slider.

 

Thank You

I don't give out solutions, but we can discuss how to solve it during my office hours.

It'd be nice if the answers to all the problems we encounter can be found in lecture slides, but that's not the case. With that said, we did cover group by queries and use of functions in class.
