Hib may I ask which centre- Xue Lin or Tien hsia is better for a secondary 2 student for me? I just passes on the dot or Chinese

Sure will heed your advice

Hi thanks your help is appreciate

HAHA. THANKS YEAHH. Any tips on how to improve comprehension?

Just education is specialized in Maths. The teacher are very experienced and friendly even though they off early, however they did a lot of revision the exam question are also mostly difficult than school work. However the teacher teaching is concise and clear I would recommend you to join the math. As for science and Chinese, I am not sure. English I not sure

Hi. May I know how to make a secondary child more Interest in Chinese. Whenever I read Chinese books I feel like falling asleep as I was unfamiliar with most of the words. I does many comprehension practice but i still suck at chinese. Please help me. I need tips ;(

Which centre is better? Xuelin or Busy bee? I need a reply ASAP! Thanks my Chinese is really weak and my exam is around the corner. Your help will be appreciate! Is Xuelin teaching pace fast. Is busybee teaching pace fast? Do they have 1-1 lesson? What is the rates? Is there a trial lesson? Btw, I am asking for sec 2 Chinese. I am checking this carefully because I don't want to pay fees for centre that are not suitable for me and end up wasting my money.

Thanks for the comment may I know what is the class size for Xuelin? Because I can't focus much on the class size. Is there 1-1?
