Standarized test was created to eliminiate minority, especially those who speak english as a 2nd language. It was made for those fast talking people to score higher. I know a few people at work that can make things sound very good even though they do not have a background in anything solid. They just have the ability to memorize and paraphrase things much better than other people.
The best way to test someone math skill is to have a long test in Calculus 4 (3D Calculus) , Differential Equation, Linear Algebra, Numerical Analysis, and Partial Differential Equation. The answer format must be in a show-all-complete-work and not just guessing C and pray. I also think the ability to show a good knowledge about math should not rest on how fast you can solve a problem but how well you can solve it and be able to explain your work.
By the way, the coordinator is racist.
