Thanks @MARIA_GONZALEZ, those are indeed the courses included in MongoDB University’s Developer Learning Path.
Learning paths are a recommended series of courses selected from the overall course catalog. There are currently 10 (or 11) individual Developer Courses per the links that @logwriter and @turivishal shared, but the Developer Learning Path focuses on 6*. The * is because the Developer Learning Path includes M220 but that represents four language-specific course codes at the moment (M220J: Java, M220JS: Node.js, M220N: .NET, and M220P: Python). If additional M220 variations are added in future, they would still be on this learning path as they have the same learning objectives.
@SourabhBagrecha and @Kushagra_Kesav described the courses and learning path approach in their MongoDB University Squad session at Community Day.
I’ll be following up with a $100 Atlas promo code
