The SAT course powered by SuperMemo is a set of 6,000 words and expressions required for the SAT/ACT exams. The vocabulary introduces words and their meanings from a basic to a highly advanced level, including definitions of low frequency of use and occurrence which might be difficult even for English native speakers themselves. Mastering this set of vocabulary items allows the learners to understand highly complex and abstract statements and texts on any given topic, as well as to formulate their own opinions in a fluent manner, yet preserving various meaning differences.
