Whats the difference between the SAT Reasoning Test and the SAT Subject Tests?
The SAT Reasoning Test (formerly called the SAT-I) is designed to test your general math, verbal and writing abilities. The SAT Subject Tests (formerly called the SAT-II) test your knowledge of specific academic subjects such as math, chemistry, biology, history, and foreign languages. The SAT Subject math tests cover more advanced topics than appear on the SAT Reasoning Test. The SAT and subject tests are usually offered on the same day, but you cannot take both at the same time. The SAT is a four-hour test. The subject tests are each one hour long, and you may take as many as three on any one test date. Not all subject tests are offered every test date, and they are not offered at all in March/April. Check the schedule carefully when planning the tests you will take.
