Succeed my IASSC BB with Sixsigmastudyguide.com
I did my IASSC Black Belt Training with sixsigmastudyguide.com I succeed. The lessons, videos, quiz are well made and help you to be efficient in your training. The learning path is clear and well defined. The team answers your questions or comment within 24h if you need help. For 60USD/month it's a very good price for the knowledges and quiz acces you get. Also all quiz questions once corrected have clear and nice explanation, which is a huge help to learn. I would highly recommend and do it again
