As for your son's political review, the background and situation of family members are usually taken into account in the results of political review. If your son's mother is sentenced to probation for gambling, it may have a certain impact on the outcome 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 affect 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 to help you understand your son's political review procedure 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, we can better understand the son's political review procedures and possible results. I wish your son good grades in the military school!
