Actually I tried to them once. I got my answers.

Please be informed that all applicants for foreign licence conversion
are required to sit for and pass the Basic Theory Test (BTT) which would
familiarise them with Singapore’s traffic rules and regulations, traffic
signages and signals. You can book for your Basic Theory Test at Traffic
Police Department, which is located at 10, Ubi Ave 3, Singapore 408865 or
at any of the following Driving Centres:

Batok Driving Centre (BBDC)

Singapore Safety Driving Centre (SSDC)

Application for conversion of foreign driving licence has to be made
in person at Traffic Police Department, 10, Ubi Avenue 3. The following
documents (both original and photocopies) are required:

Ø BTT result slip indicating the passing of the test.

Ø Passport and NRIC/Entry Permit/Employment Pass/Dependent Pass/Social
Visit Pass/Work Permit etc (whichever is applicable).

Ø A valid foreign driving licence.

Ø An official translation of the foreign driving licence from the
relevant Embassy/High Commission if it is not in English.

Ø Extract of Driving Licence from the Licensing Authority, indicating
the date of first issue of the foreign driving licence, if it is not
already indicated.

Ø A passport-size colour photograph with white background and a
matt/semi-matt finish and a fee of $50.

So I hope that the information given has been beneficial to you.

I think you no need to worry about the convertion. I stay here for more than 3 years and I got my licence in china 5 years ago. At the early of this year, I suceess to do so. And most surprisely, I got my temproraly one on the spot. Very impressive.

BTW, Class C is enoght unless you want to drive some like a Truck or 坦克。Moreover, Motor license is not included in the C. If you get them all in China, you can also get them all here, only in 1 year probation.
