Now that we know you aren't speaking common English, what are we supposed to make of your statement? Once you start making up your own definitions for common terms, your ability to express your thoughts to others goes away.
What do you mean by "best grades"? What do you mean by "deserve"? How would you even know if the black person (or Hispanic or woman) who beat you out of a job was not more qualified for the job? Would believe the manager who decided not to hire you if they told you so?
Your problem is you have little understanding of today's society. You should seek help.
