First of all, the tests should be free. They should be given on a small scale, preferably by each school or department, and scored by the teachers at that school, though the students' names should be anonymous during scoring. The exams should test students on the actual knowledge necessary for their chosen fields of study. If a general test is necessary, it should not be limited to high school math and vocabulary. The tests should be as comprehensive as a student's education. Finally, entrance examinations should not be multiple-choice based. Essays and short answer questions are the only questions that truly measure a student's knowledge, creativity and ability. All in all, entrance exams should be the exact opposite of today's standardized tests.
Basically, Anika calls for the GRE's to be abolished ,and for the actual tests to administed by the universities themselves, more focused on short answers and essays ,and the new exams to be free of chrage.
If you can take the same suggestions to the SATs, I promise you that it would be much different from the current SAT's,and that would be a good thing.
