How about being a soldier in senior year? What is your policy? Age requirements and so on. Who knows better? Give me some instructions.
I suggest you come back after you get your diploma. First, you can get a job. As long as you get a third-class merit, there is basically no problem. Second, if you don't start to work, set up non-commissioned officers, and add four years of school age to length of military service. Three years for others is three years. Three years is equivalent to seven years. And if you are a soldier now, you can refund all the college tuition, which is also quite awesome, much better than going out to find a job.
