NY Regents Test Prep: Algebra II/ Trigonometry— Advanced Academics New York Regents Test Prep: Algebra II/Trigonometry is designed to help you prepare for the Algebra II/Trigonometry Regents Exam by providing an extensive review of key concepts most commonly emphasized by the exam. Each unit begins with a diagnostic test. If you pass the diagnostic test with a 70 percent or above, you may skip the lessons and tests for that unit. This allows you to focus your attention on the areas of study in which you need the most help. Each unit also contains two practice tests with problems similar to those you will face on the Regents Exam. This is not a full semester course; how long it takes you to complete will depend on how well you perform on the unit diagnostic tests. It is recommended that you complete Algebra II and Trigonometry prior to taking this test prep.
