Free SAT Vocabulary Practice TestsVocabTest's SAT Vocabulary: No registration, 2400 Vocabulary questions. At the bottom of the page, there are links for Level A - Level H. These are quizzes you should take. Difficulty appears to increase in higher-lettered groups. Each Level has 15 "Units" of 20 words each. There are several different formats of the multiple choice questions: Learning Definitions (gives you a word), Reverse Definitions (gives you definition), Synonym Practice (gives you word), Reverse Synonym (gives you synonyms), Antonyms Online (gives you word), Reverse Antonyms (gives you antonyms), and Vocabulary Sentences (complete the sentence). The Antonym quizzes are not available in Level A, and the Sentence quizzes are only in Levels D - G. If you miss a question, you go back and guess again. Remember the correct answer, because every question you miss appears a second time later in the quiz. This repetition is an excellent learning tool. When you complete a quiz, a page comes up showing the questions you miss for a final review, and it compares your results to other users' data. Between the huge number of quizzes and the many ways to take them, VocabTest's site is a great place to study vocabulary.
