Quant From Big Book

Hi,
I am planning to take the test 1.5 months from now. I had one question, is doing quant from the big book worth the time. Currently doing 5lb for practice and planning to start with https://www.gregmat.com/skills-quantitative.

Thanks!

On the whole it’s easier than the real GRE but I still found it extremely helpful for refreshing fundamental skills. Every #28, #29, and #30 is the same difficulty tier as a current GRE problem, and the Data q’s are worth doing too.

Solving official material + Manhattan 5 lb = More than 2000 questions. Do you really need to solve Big Book after that?
