Error in documents,got admission by claiming reservation what to do

I got admission in a govt college by submitting exserviceman ward certificate-disability of exserviceman shown "attributable to military service". certificate issued with seal & sign of authority but not on letterhead nor having any number. counselling panel and original documents verification team also did not raise eyes and gave me admission. Actually I am ex-serviceman ward-disability of exserviceman is "aggravated by military service". Half duration of my degree course passed. If one complains against me then 1. Will i be allowed to continue the course? 2. How much chances are there that college may lodge FIR after expelling me? 3. Is it fake document/forgery/cheating? 4. How much is punishment & is is bailable? However, nobody knows about it so far. 5. Now If i withdraw my admission, am I safe? Or still if one complains, how much chances that college may go for police case while I have already left the course? 6. if I complete course, nothing happens, will degree be valid?
