This will benefit people with time, money and guidance (both guidance counselors and parents) geared towards getting students into top colleges.
Presumably that will result in an increase in scores overall. Since essentially the point of this test is to compare students to each other, that means everyone who does not utilize the multiple test strategy will have a score that is comparatively lower.
Honestly it probably helps my family because we are in the know and able to game the system. But overall it’s a net negative. It just gives another advantage to students who are already at a massive advantage.
