Working in Singapore during study.

Dear fellows, I'm from KARACHI PAKISTAN & have done my MBA now want to join Singapore as student for my further studies. Please inform me that:
1. Does the Singaporean LAW allows to student work during the   
   study? If LAW allows;
2. How many hours a student is able to work?
3. And what's the monthly expense of a student in SINGAPORE?
4. What's minimum per hour wage in SINGAPORE?

I'm hopeful that any one of my fellow will help me about it. thanks a lot.
