Mr Ang is a very nice and chill teacher. He is really knowledgeable in Maths. His notes are very useful. Although each lesson were short(2h) but it has covered all the important points. He split learning points so we can focus on certain learning points for that lesson. The pace of the lesson is just nice for me. If I cannot make it on the scheduled lesson, there would be make-up lessons as well. He also help to give advices for my university courses. I recommend him for those who want maths tuition.
