Quant sectional tests

Hi! I was wondering where I can find 35-minute sectional tests for quant aside from the Official guide, math review, and Manhatten 55lb? Also, are the big book questions representative of the actual GRE for quant?

The best material will always be ETS. Big Book is a little “easier” than the actual GRE, but try going through the test following the rules i.e. 30 minutes with no calculator. Then it becomes more challenging!
