I'm talking about engineering grad school (MS). When I say entrepreneur I'm talking R&D for new products/technology/small start-up. Would it be more useful to: A. Keep an existing full time job while going to school part time (paid for by the company with 3 years service after degree), save up money while learning, then start a business. Get a PE in the process. B. Go to grad school full time and specialize in a related field, get out and work for a year to save enough to start up or look for venture capitalist funding. In order to get a PE you need 3-4 years work experience right? That may play a factor since full time school wouldn't count. C. No grad school, continue working to get a PE and save enough to start independent R&D without an MS. What do you think?
