Sigma Academy is not just another tutoring center. The directors, Dr. Gowri Narla and Dr. Swapna Gurla, started this institute with a vision to provide a place for high school students to not only master math and science skills, but also to develop a passion for the subject. They are concerned parents who understand the anxiety of other parents. Both Dr. Narla and Dr. Gurla have over 25 years of scientific research and teaching experience with a thorough understanding of students' needs. We helped high school students at all levels to confidently tackle the challenges involved in taking Honors or AP Courses, as well as the College Board SAT Subject tests. We proudly claim that we have been very successful in the role we have played in helping our students attain their academic goals. Most of our students have performed very well with excellent scores on both the AP exams and SAT II subject tests.
