SAT
Scholastic Assessment Test (SAT) is composed of two parts SAT I and SAT II.
The best ways to get ready for the SAT I:
Reasoning Test is to take challenging academic courses and to read widely outside school throughout your school years. Preparation for the SAT II: Subject Tests varies for each test. For example, some Subject Tests (such as American History, Biology E/M, Chemistry, and Physics) are best taken as soon as the course ends so the information is still fresh in your mind. You'll do better on other tests, like Writing and the language tests, after several years of study. Make sure you know the test directions, know what to expect. Do the easy questions first. Know how the test is scored. Guess smart. Don't panic if you can't answer every question. Omit questions that you really have no idea how to answer. Be careful when filling in the grids Use your test book to do scratch-work Know your answer sheet. Don't make extra marks on your answer sheet. Mark only one answer to each multiple-choice question
