 Precalculus
 Precalculus Course Highlights Structured program aligned to High School Precalculus. Live classes by high achievers from Ivy League Schools. Dedicated class time for review of Students Requested Questions. Assigned homework comprising of problems and videos. Class forum to facilitate peer and expert interactions Course Description This course is designed to cover topics in Algebra ranging from polynomial, rational, and exponential functions to conic sections. Trigonometry concepts such as Law of Sines and Cosines will be introduced. Students will then begin analytic geometry and calculus concepts such as limits, derivatives, and integrals. This class is important for any student planning to take a college algebra or college pre-calculus class.
