You have to understand that many institutions are irresponsible when signing up. You can buy one of their books first and see how their training materials are. If they are well organized, you should think about it. Don't blindly follow the trend. After all, tuition fees are not blown by the wind. After reading their books, you can also ask their former senior sisters. If you can, then you should implement it quickly and ensure that you can be admitted next year.
