First of all, we should contact the local medical institutions as soon as possible to ask if we can fill in the missing items and understand the process and cost of make-up inspection. If you can make up the exam, you should arrange it as soon as possible so as to complete the physical examination in time.
Secondly, if the make-up exam is not feasible, you can try to provide other supporting materials to prove that you have no missing diseases. For example, you can provide a health examination report for a period of time in the past, or provide a doctor's diagnosis certificate.
Finally, if the above two methods are not feasible, you can try to apply for special approval from the school to avoid being affected. The school may require some other proof materials to prove that it has no missing diseases.
In short, there are three ways to solve the problem of missing one item in the college entrance examination: make-up exam, provide other supporting materials and apply for special approval from the school.
