Not too loose. There are three types of math test questions: fill-in-the-blank questions, multiple-choice questions and answer questions. The reference answer and scoring reference formulated by the Ministry of Education only give answers to fill-in-the-blank questions and multiple-choice questions, and there is no specific derivation and calculation process. If you answer each question correctly, you will get 4 points; if you answer it incorrectly, you will not be backtracked. So for multiple-choice questions, encourage candidates to guess the options if you can't answer them.
