No Kris Lau for sure. He's a lot of plans which are unnecessary. He speaks loads of nonsense. Last time he spent like 3 hours focusing on section B2 reading DSE practice paper. If you do the paper on your own, you'll need less than half of the time. How on earth did he spend so much time then, you ask. Well thanks to his poor singing, I've learnt to appreciate my own singing. He sang stuff like 'let me go' To join ONLY ONE OF his plan, you need double the time need for other tutors because you take 2 consecutive lessons on a day. He teaches using past paper which you can do on your own.
Of course, I doubt his English standard. To judge one's English level, the accent may not be an accurate indicator but the deviation is little. I'm going to tell you that his typical Cantonese English accent doesn't give me much confidence in him, let alone his inaccurate pronunciation.
He doesn't deserve almost $700/4 lessons.
Sorry for my mum's money.
What I dislike him in particular is that when I went for his first lesson, he asked me which school I came from. Also, he doesn't teach even in his live lesson, no matter which room you sit in.
