I submitted my homework correctly here -> https://university.mongodb.com/mercury/M121/2019_August/chapter/Chapter_1_Basic_Aggregation_-_match_and_project/lesson/5970d8b78cf2c5580eef7d8b/problem. I got frustrated since I struggled a bit but in the end, I submitted the correct answer. Can somebody help me to figure it out if it was some deadline issue?
The deadline for Chapter 0, Chapter 1 and Chapter 2 was August 27, 17:00 UTC. So you will not be able to submit the answers after the due date has passed.
Please make sure you abide by the deadlines in future.
Good Luck for the course!!
Please let me know, if you have any questions.
