The material is very well planned as a logical progression. It makes the statistical tools very easy to understand and their relevance becomes clear. I had some of these statistics tools when studying for a BA in Economics, but then the tools were abstract and theoretical. It took me 2 months to get through the detailed material, then 2 weeks some time later to go through the shorter version study guide after which I could take and pass the exam in the first try (93% correct) with plenty time to spare. And having access to the material afterwards will be useful for when using it for work. All in all, I can clearly recommend this accredited training and certification!
