The new ‘Test your knowledge’ evaluations viewable from the syllabus page are a good idea. However, we aren’t told which questions we answered correctly or incorrectly. I took two in the ‘Data Scientist: Analytics Specialist’ career path, and neither told me what questions were answered incorrectly. The ‘Review Concepts’ option presented with the test results just dumps you back into the beginning of the syllabus.
It would be more helpful to know what to work on further.
