Firstly, if you have the foundation, you can get the license in the crash course, because the New Oriental itself also has the class for the license, you can apply for the examination.

Second, if you do not have the foundation, it is clear that the chef can not be a crash course, you can not take the test, can not get a license, you need to learn first.

This answer if there are inadequacies please understand, I hope to help you, I hope you can take in time, I would like to express my thanks! Have a chance to see you next time!
