With 6 weeks left and the whole syllabus for the SAT II Math 2 Subject Test to be covered, I felt hopeless and stressed. Thanks to my tutor’s enthusiasm and positive energy, I got over the fear and managed to learn the whole syllabus in 6 weeks! The tutor explained things thoroughly and made the classes fun. He always made sure I understood everything. Thank you so much - I wouldn't have been able to do it without you!
