I graduated with a Bachelor's degree in Mathematics and has units in Master's degree in Statistics. My specialties are Algebra, Trigonometry, Geometry and Calculus. I can also teach Singaporean Math in Grade school level. I am very confident that all my students will learn Math in a friendly way. My approach is to figure out how the student understand the topic. I test them first if he has knowledge about the basic Math before going through the topic. You can expect me to be well-prepared on any topic. I can help you by providing all possible problems, not just 2-3 example problems but at least 10-15 examples that might appear in your quiz or exam no matter what textbook you are using. I have experience in tutoring different kinds of students in a tutorial center until I work independently as a Freelance Math Tutor. I love teaching kids and teaching is my passion.
