Find more practice

After finished M121 course, I want to have more practice in “The MongoDB Aggregation” and strengthen query skill. Does anyone know where can find more lab questions (problem & solution) in online resource?

Hey @infotomorrow

I am not sure about other courses but I would recommend reading the docs over and learning about all the aggregation operators.

Perhaps you could also try building pipelines and running them against the MongoDB Atlas cluster that was provided.

Also building applications has really help me learn more about MongoDB. There is a lot that is not covered in the courses. :wink:
