Regarding your son's political review, the results of political review usually take into account the background and situation of family members. If your son's mother has been sentenced to probation for gambling, this may have a certain impact on the results of the political review. However, this does not mean that your son will fail the political examination.
If you are worried that this situation will have an impact on your son's political examination results, I suggest you contact the military school admissions office to consult their policies and requirements for this situation. They can provide more specific and accurate information and help you understand your son's political review procedures and possible results.
Finally, I must emphasize that the result of political review is often influenced by many factors, so there is no guarantee that your son's political review will pass. However, by contacting the military school admissions office and understanding the relevant policies, you can better understand your son's political review procedures and possible results. I wish your son good grades in the military school!
