Hello and welcome to our Practice Field! If you felt like the exercises were not enough at any point of our course, here is a place where you can solve further window function problems.

The last part of this course, part 10, is a Final Quiz, which you need to complete in order to successfully finish this course. We are aware that window functions are a powerful tool which requires practice and review. This is why we created this part – it does not introduce any new knowledge, but it reviews everything you have learned so far, part by part.

In each section, we'll quickly review what we learned by introducing a single example to refresh your memory. Then, you will be presented with some exercises. Know the answer right away? Fantastic! Need some help? Don't worry, each exercise has a hint which you can check.
