Before I answer, here is an important thumb rule. If It Sounds Too Good to Be True, It Is. What it means is that any venture that lures you into making profit or quick money is most likely a scam or at best dishonest.
I can speak with some authority on digital (was head of digital for a multinational, setup digital ventures, written articles and taught digital at universities) and I can tell you from experience that there are enough charlatans in the industry who can con you into making a quick buck.
So stay away from this course or anyone that makes such claims.
Well then what about those who want to genuinely make money from the medium? The good news is that digital and e-commerce have made people rich, but you need to understand the basics and follow the regime I've outlined below ...
Watch webinars and videos on digital, especially on YouTube (treasure trove of digital knowledge). SlideShare is another useful resource that provides you short guides on digital, especially the ones created by digital leaders and influencers.
Practice your skills by setting up a Wordpress blog for free, create a content plan (using keywords or topics that are popular or trending), create a social media action plan to form a community and attract audience organically to your blog. Try, Fail (which you will most certainly do), Try Again and get better with each try.
But trust me the practice and persistence pays, there is no shortcut.
