Guidance for CIE A level

Hi!
We have just moved in to Singapore ten days ago. My elder son has finished his CIE AS level exams last month. We are unable to find a school here who can help him in CIE A level preparation to take exams in May-June 2016. Can anyone help?
Alternatively, if my son does home schooling for this year , are there any good coaching centres for CIE A level Physics,Maths,Chemistry and Business Studies?

What is CIE?
You must apply for exemption from MoE to be allowed to home-school your kids in Singapore:
