Generally speaking, it depends on the level of the school and the city where it is located, because the applicants are different. Relatively speaking, key universities in big cities are not easy to test, and schools in the second district are relatively easy to test. Therefore, whether the exam is good or not is relative, that is, it depends on which school you compare with: it is definitely better than the 985 University of Science and Technology in the first district, but it is not as good as the 2 1 1 school in West Africa.
Whether it is good or not depends on everyone's performance and preparation. It is good to be ready before the exam, otherwise it will be bad. If you plan to apply for the exam, you must be confident and diligent, because admission depends on the results of the initial test and the second test.
