You should read the requirements of the materials carefully and write down your study and work experience carefully.

Jinghu education doesn't know much about it. You can listen to their open classes and see if they are credible. At present, many institutions provide pre-test counseling for MBA students, so keep your eyes open. All those under the banner of insurance are deceptive.
