Lab too difficult?

I’m following M121 course. I find the course done very well, but in some cases, the labs are difficult to deal with also because to solve them you need to use functions not covered by the relative lesson.
In some cases, it is frustrating not to be able to solve a lab by trying to use what was explained in the lesson.
E.g. in the lesson 2 lab to solve the problem, I’d use $setIntersection not easy to find.

Hi @morellik, welcome back to the community :wave:.
Thank you so much for reporting this.
We try to cover as many aggregation operators and stages as possible in the course, but some of them are left for students to learn on their own using documentation. $setIntersection was one of them.
However, if you feel the same for any other lecture/labs please let us know and we will be more than happy to forward your feedback to the curriculum team.

Thanks and Regards.
