If the primary education from junior college is easy to test, the general content of the test is English, politics and professional courses. There will be an exam outline and materials in the exam. As long as you can master it all, there is still no big problem in passing the exam.
It is not the exam itself that is difficult, but the key is whether the exam is unified or selected. The actual admission is based on the enrollment plan of the college in that year, combined with the scores of the candidates. If you score high and rank high, you may be admitted.
