Singapore Medical Council requirement on Conditional Registration

Dear Expats,

Can someone help me to clear the below questions I have with regards to conditional registration for general practitioners; (please note I'm not a professional in the health care industry)

1. Is it a must to have an offer of employment from a SMC recognized medical body to be eligible to apply for the conditional registration?
2. I have noticed several Levels of conditional registration i.e Level 1, Level 2. what does it mean? Can you please please provide me with links to some further reading on these different levels of registration?
3. It is a requirement with SMC that the candidate should hold a 3 years of clinical practice to be eligible to apply for the conditional registration. Does the two years the candidate spent on houseman-ship be regarded as clinical practice?

I understand that some of the above questions maybe very basic but considering me being from a non-healthcare background I would seek some advise from you.

Thank you folks.

Cheers
