Affiliate Marketing Secrets

Hi every body.. iam persuing my 1st sem in a college affiliated to barathiyar university.. recently there was a fight in college between me and the other guy.. in which i slaped him inside the computer lab.
the guy was the cause for the problem,,, “he created a rumer linking me and my class girl who was like a good sister to me” now the principle of the college has suspended me for 3 months and he even not allowing me to take my semester which falls during my suspended period…..
Hence my question is dose a principle have rights to stop me from taking my university examinations??????????
