I have a congenital heart disease and can't do strenuous exercise. Can you go to college without military training? And if you don't go, will you break your promise?
As long as the hospital issues the relevant diagnosis certificate, you can not participate in military training. As for credits, each school has different requirements. Some schools don't accept military training credits. However, specific issues need to be negotiated with the school. But as long as your situation is true, military training is definitely not necessary.
