The SAT focuses not just on a basis of prior knowledge and vocabulary, but on students’ problem-solving abilities. SAT test prep courses help students build stronger critical thinking skills in order to maximize SAT scores. We average an increase of 300 points on the SAT and 10 points on the ACT. Many colleges, particularly the more selective ones, require or recommend certain SAT Subject Tests. These are hour-long, multiple-choice tests offered in 21 subject areas. SAT Subject Tests are an excellent opportunity for students to showcase their particular strengths.
