DataStax Academy migrated to a new learning management system (LMS) in July 2020.
The new LMS is a completely new platform with nothing in common with the old system it replaced. Due to this limitation, only the progress of fully completed courses (100% complete) were migrated to the new Academy site.
The progress of partially completed courses in the old site -- even for courses which are 99% complete -- will not be reflected on the new site.
I managed to check your progress in the old site and found that you've completed both DS201 and DS220 so you don't need to do them again:
Please note that your course completion progress is not a pre-requisite to sitting the certification exam. This does not in any way disqualify you from booking an exam.
Thanks for staying with us through the transition. Cheers!
