GRE Big book long passages lengthier than actual GRE?

Hi,

Can someone tell me if the GRE big book long passages are longer than what will be coming in the actual GRE or is it at par? Also difficulty wise is the GRE RCs more difficult than the Big Book passages?

It depends.

I felt they were on the same level but then again its my personal opinion.

Aah okay thanks. Much appreciated!
