Next course for developer after M001

Good Morning,

Can any one suggest which course is good after M001 as a developer.

Once you complete M001 you will get a mail suggesting next courses
Most likely these:
M103: Basic Cluster Administration
M121:The MongoDB Aggregation Framework
Course instructors can give better suggestion on this

Hi. As the user above suggested, M103 would be a great place to further advance your learning in MongoDB.

Please let us know if you have any questions. We are happy to help.

I registered for M121 and I’m just about to start it. It sounds more relevant for developers than M103, which sounds like it’s more aimed at DBAs. I could be wrong about that of course, having not done either of them yet.

M103 is seems for cluster, is it for DBA or developer
