Dalian GSP Training School is a fool and has no credibility at all. It didn't pay the Pratt & Whitney voucher to tell it was free, but it was charged immediately.
Pratt & Whitney vouchers used to be a good thing, but now the essence has changed. It is said that you can't learn real skills with that thing. What can I learn with so little money? They are all low-level skills. There is no such thing as pie falling from the sky. Don't be greedy and cheap. You'd rather spend more money to learn some real skills and find a good job.
