The instructor was good at this subject, he directed the light on some basic and important points about the subject. however, I believe the course would've been more effective if the instructor would've appeared in the videos

I gained more knowledge about sales through the course but I the explanation on marketing and the differences between marketing and sales could have been more elaborate.

I just loved this course. There was a project I had been working on for ages and it wasn't going anywhere but suddenly with this course, the whole structure of my screenplay came out effortlessly. Sorin is also an incredible instructor, his positive energy is highly contagious. I am a big fan now.

I am a very logical person. When ever I learn something, I try to picture out a whole process of what I need to learn and to do. This Mini Course is perfect for me to have a general idea what I need to put my first funnel together. It is a mini course but it also goes very detail of how to actually doing things.

Great delivery on interesting content. Like the positive attitude of the teacher, with alot of small tips/advice. The summarize on the end of the chapters are great too. Also there is additional pdf files included so you can learn the stuff with different learningstyles.

Excellent quick introduction to Sales. Very precise fundamental course and good starting point. Easy to understand and the quiz element is a ideal indicator of your own understanding of the course. I liked the way the course is defined as a beginner I am able to understand things around sales.
By Biaggio Nepi on 4/6/2017
Great explanation of his approach to the sales process. He relates selling to other real world experiences that most people don't see a relation. Very helpful for making sales less boxed. The course was interesting for me as an outsider to the sale's area, though it was a bit focused on one sales strategy.
By Louise Vermeiren on 12/13/2016
This course contained lots of good information that I did not know about how to start a successful business selling. I liked how Sorin seemed to really want his students to succeed. I will be taking him up on his offer to evaluate my storefront once I get it up and running!
By Kees Buij on 12/4/2016
I absolutely love this course and the way Sorin presents it. I am learning heaps from it and it definitely helps me to become a better coach. It answers many questions and talks about many topics I have always been thoroughly interested in learning more about. I can't remember the last time I attended a course that I was so genuinely motivated in following through.
By Brooke Williams on 6/14/2016
I have done other sales courses in previous years, so this course didn't teach me anything new; it just refreshed my memory on everything I have already learned, but in a less sophisticated way; it's a lot easier to understand. One small problem, all the 'match the stage/process with the example' activities at the end of the slides are already in order - this doesn't create the challenges necessary to consolidate the lessons learned; it's just a quick recap of the entire lesson.
