One star is too much!BigDev course is just a joke, full of broken links and misinformation. Made a complaint 3 months ago asking for my money back and they are still making me go in circles.This is a joke of a company, their customer service is just poor when you complain about anything. They make you believe that you are being attended to and they are just playing with you and your expectations.AVOID at all costs, not only the courses but the platform itself.
