Microsoft's edX courses
MTA certifications include exams for https://docs.microsoft.com/en-us/learn/certifications/exams/98-388 and https://docs.microsoft.com/en-us/learn/certifications/exams/98-381. Why's your https://www.edx.org/course/introduction-to-python-absolute-beginner-2 not open to new enrollments, unlike your https://www.edx.org/course/learn-to-program-in-java-2? Since you don't have a certification for R programming (to support https://mran.microsoft.com/download), why's https://www.edx.org/course/introduction-to-r-for-data-science-2 also not open to new enrollments? Thanks.
