Are the solve quant questions on gregmat website from old GRE big book?

I have my GRE exam in 2 weeks, I am not sure if i can solve and practice the quant questions from all different official sources. Right now I am just using gregmat solve quant problems,the current official books and manhattan 5lb book. If the questions on the gregmat solve quant problems are from the old gre big book I will be relieved. Just curious to know

Thanks in advance guys.
Cheers and all the best
