It's a very interesting lab, but it needs more time for the student to complete it. I wasn't familiar with math concepts like quantiles and the analytical functions (I come from a mainly development background, not data engineering), so I spent a lot of time reading the docs on the functions and playing with variations of the queries in this lab. I feel like an extra 30 mins would have helped me feel less rushed.
