How can I get my course completion confirmation?

over all I got 69%, but I couldn’t see any certificate download. M001 MongoDb basics course completed on Jan 29.

From overview tab you should be able to see status
View completion confirmation click on it and download the certificate

Just for confirming, this is a course completion confirmation.

Certification is different and you can get more details here: https://university.mongodb.com/certification
