SY0-201 Practice Questions

Hi,

Is there alot of difference between sy0-101 & sy0-201? Im in the middle of studying for 201, and im limited to the practice questions in my Sybex book, pretty much all the practice questions I can find online are for 101.

Is alot of the stuff in the 101 exam questions still relevant, or can anyone point me to some 201 specific questions sets?

Thanks alot.
