Unlike the social sciences, you cannot BS your way through a math test. You can shout at the paper all you want, call it "racist!" and any other names that come to mind. The paper doesn't care.
You either "get it", or you don't. Your answer is either correct, or it isn't. It makes no allowances for how "oppressed" you feel.
Well duh. Two plus two equals twenty two.
It's easy to get pissed about this stuff, and I feel your pain.
But you're being unreasonable.
There are high schools in the US where the average IQ is 85. The AVERAGE.
The system we have created, or allowed to be created, says that every student who is not severely mentally ill or who does not die of homicide or a drug overdose CAN and SHOULD complete 12th grade and receive a high school diploma, and that when the number achieving this is less than 100%, it's because of bad teachers, inadequate resources, or the wrong curriculum.
People with IQs of 80-90 do not fail Algebra II or trigonometry because they feel oppressed. They do not fail because they accuse their teachers of racism.
They fail because their schooling should have ended after fifth or sixth grade. They are bit players in a macabre morality play, scripted by white wannabe saviors who believe that, if only badwhites are stigmatized and goodwhites make up for imaginary "racism", then the five year plan will be fullfilled.
The systematic accusation that blacks are failing because the educational system is racist is correct, after a fashion. Except the racism that the system stinks to high heaven with is the racism of goodwhites who lack understanding, or who are afraid to face, the consequences of the Frankenstein monster that THEY have created.
The students with IQs of 80-90 who go to high school every day and are enrolled in math and science classes where they don't belong and in which they cannot achieve are not the cause of systemic failure - they are the victims of a failing social experiment which, since it cannot be modified is taking all American schools down with it.
