Mr Ang is a dedicated teacher who will readily help you, even after class, with any math question you've faced while revising. Before attending Mr Ang's lesson, I have always doubted the effectiveness of a class tuition. However, i was wrong after attending his lesson. Mr Ang usually keeps his class size small to ensure that each student will comprehend the concepts extensively. His notes includes questions of varying difficulties for greater exposure. Also, every lesson is recorded and uploaded for the convenience of students who wish to re-visit a certain concept. With his guidance, my math has improved greatly. Thank you Mr Ang!
