1, your physical condition is out of the question, and you are still qualified. Generally, about 300 degrees is enough. 500 degrees is a bit high, but you can still find some relationships. Military training is not devil training, and ordinary people can accept it. The key is perseverance. This is especially true for recruit training, which is actually a little more tiring than school military training. In the recruit stage, the main thing is to get you into the habit of being a soldier. Usually, I mainly do housework, study rules, political education and military training, that is, queue training, basic individual tactical movements, basic shooting, Grenade throwing, basic physical training and other subjects. The assessment is mainly a military subject, and it is necessary to test rifle shooting (now it seems to be changed to probability shooting, and 10 only has 3 rounds). Grenade throwing (which is the highest risk), queue action and individual tactical action. Physical fitness mainly includes: 3 km running, 100 m, standing long jump, legs squat, sit-ups, etc. The standard is not very high. I think ordinary people can get by with a little training. In the future, the life of the army will be much richer. There is physical training every day. Most of them run 5 kilometers, sometimes armed with 5 kilometers, but they are all gradual and will not give you an increase at a time. A little more difficult is exercise, camping, hiking and marching.
2, 3, winter conscription is an ordinary conscription, and when you arrive at the army, you are an ordinary soldier, not because of what you study.
What preferential treatment will you get? Everyone depends on their own performance to determine their position. Military quality and political quality will not say that you are a college student. He is a junior high school student, so you can train less or enjoy more treatment. Being a soldier means being a soldier, exercising your character and dedicating your youth. Although it will not directly help your career, it will benefit you for life in transforming your character and enhancing your perseverance.
