is a united malaysia a myth? (2) University

Everybody knows that you'll see majority malays in public university and majority non malays in private university... Why is this happening? Are the non malays richer and the malays poorer? Nope... The answer is there exist a quota in public university.. Only matriculation and STPM students can enter them... Guess wat.. Only 10 percent of non malays can enter matriculation... That is what they say... I personally think its less than 5 percent. And STPM? Its the second hardest exam in the world... Plus, public uni prefer matriculation students than STPM students... U do the math... In my class during my STPM years, there are no malays in it.. So, how can non malays get in public U?
