I just finished the course right now. I thought I would struggle far more than I did:
Being almost a total ignorant in business admin in general, and business planing (at least decent), mr. Timmermans has been able to do a comprehensive, yet crystal clear and friendly course that has changed my perceptions, knowledge and surely my professional future with his course.
I dearly recommend it!
I’ve enrolled fot the “damn Good Business Plan” too, to make sure that I do not miss anything on developing business plans, but I think this could already be enough to star designing any small business.
