Next time speak to tutors. Ask about their teaching style. Ask how they handle discipline matters or when homework is not done. MOE teacher does not mean they can teach. They have gone through a course, but it does not mean they can teach.Parents have to take a proactive role in finding tutors. Role of tutors is to close the gap in a topic/subject. Role of tutors is not to teach, but the system in Singapore is such that tutors end up teaching as well. Just learn from experience and move on. All the best.
