What do you think of my rap?

Just something I wrote in a couple mins,looking for some honest opinions. Brain full of knowledge,if I told you I didn't go to college you wouldn't believe it,my breath's so valuable others wanna rebreathe it,im heated when ****** say I cheated,face it you competed but your progress was impeded,stopped in its tracks,and whoever attacks,will be defeated,now hear me people when I say were not equal I mean it,on the next level believe me I've seen it,no ***** ****** there's a prescreening,and if you don't believe it,step through and well see who still maintains breathing.
