I took the GRE subject test.

There is a test that students take to apply for graduate school. There are two different types of this test. There is a general test, and there are subject tests. The subject tests are very specialized, and they cover very detailed subject matter. I took the GRE subject test. I applied to graduate school, and the test that I took was geared toward the subject matter that I would be studying in graduate school. The subject matter was based on the area that I planned to enter.
