SAT words are carefully selected to test student's English proficiency of reading and writing in their daily lives as well as in school, which, in terms of Word Frequency of Occurrence (WFO), lies in a certain WFO range.

Through an extensive search, we have identified a WFO range for the SAT's. This is the key point setting us apart from all of the other SAT TEST PREPARATION platforms, whose SAT words are all based on words that occurred in the earlier SAT's. Indeed, our SAT database includes all of the earlier tested words. However, it also contains the words with high WFO for SAT, but have not occurred in earlier SAT exams yet.

We have arranged each word by its WFO index in addition to the conventional ways (alphabetical, grade level, etc.). This will give students a choice of studying the words according to their time schedules. For instance, if a student is in a rush to take SAT's, he/she may just study the first 3000 hottest words.

To help students quickly remember these words and mimic the real SAT test, we have added synonyms, antonyms, examples as well as the pronunciation to each word in addition to the explanation (in both English and other foreign languages).

For an average student, he/she can finish the entire word list (>5,000 words) in less than 80 (accumulated) hours.
