lgr1016's honest review, How I Built 350 Personal Apps to Achieve 7x My Monthly Salary in Revenue course

Is this really worth 400,000 won...? I also generate revenue from apps and took the lecture to scale up, but isn't this level of knowledge something you'd know to some extent just by launching a personal app...? There's nothing specific and it's all vague, and it seems like it's a lecture created for income diversification because they feel insecure with just app revenue...
