In the written test, if you have a certain foundation, personally, you are not advised to sign up for classes, but if you are a white student, it is necessary to sign up for training classes. Passing the written test is not the same as arriving at the interview. An interview is different from a written test. You can't get by by working hard. There are many points and details in the interview.

As for how to choose a training institution, again, it doesn't matter if you don't report the written test. Be sure to apply for an interview. You can visit Dashu. Of course, the choice is yours.
