Geometry and Probability material

[frappy2u]

Hi guys,

I am taking GRE in 20 more days and i need more practice on geometry and probability questions, Caz every time when i am doing some practice test, i am unable to solve the difficult geometry questions, and most of the time my geometry questions go wrong. So, cud anyone suggest me where can i find more of geometry and probablity questions to practice. And i already solved barrons material and i found those questions not to difficult. would it be enough if i also solve math from kaplan GRE exam book or do i need to practice some additional material apart from barrons and kaplan. I would highly appreciate if anyone cud give me their valuable suggestion.

Thanks in advance.
