1) when you receive the admission/contract the business school can cancel your admission?
A: I'm not sure I entirely understand your question. You can always choose not to attend or drop out, but it depends when and you may not get your money back. Timing is key. The rules are very school dependent. Can you clarify or share more?
2) if you pay the deposit and you sign the contract before the scholarship decision, do you have any possibility to receive a scholarship or they know that you are going to attend their program and they tend to not give you a scholarship??
A: The schools do not penalize students for commiting. If anything, you could argue you might have a better shot at getting scholarship money as the school know you are attending and it might be more interested in helping out matriculating students as opposed to those on the fence. Of course, you could argue the flip side that the school could use the scholarship money to entice undecideds; however, generally if those students don't end up accepting the money, it is subsequently redistributed. Point being, you should not be afraid to commit if that's where you are going for fear of losing out on financial support.
