Help in getting Certified

I want to do the certification " C100DEV:
MongoDB Certified Developer Associate Exam".
However when I click on the course it shows " Retired | M101N: MongoDB for .NET Developers (Version 3.2)".

How can I access the course to prepare for the exam. Thank you!

The FAQ shows why the course is being retired…

The old M101P Python course has already been replaced with an M20x level training. I reckon the .Net training will return soon, as M20xN.
