Decoding the EST, ACT, and SAT reading and writing exams. The American Diploma students face a lot of challenges. The biggest one is how to understand fully and deeply what is written to be able to choose the correct answer. In order to achieve this goal, students must be equipped with suitable information - History, Scientific theories, and Vocabulary - that will facilitate their mission and realize their goal. I offer the students everything to establish a proper background in all subject matters related to the SAT/ACT/EST exams.
