mattdrayer Posted January 30, 2023 Share Posted January 30, 2023 I’ve worked for edX since 2014 — PredictionX is a popular course that has received a lot of positive feedback, although I haven’t gone through it myself yet. Definitely a good one to flip through for free even if you don’t want to pay for the full certificate track! Matt Quote Link to comment Share on other sites More sharing options...
