Gre groups of questions material

Hey, how do you guys practice time management for quant and verbal? Time management is not on an individual question, rather blocks of questions just like on the exam. For quant, I’m using magoosh atm, but was wondering if you guys use GMAT book and randomize them to do blocks of questions, how do you go back and forth with the questions and pages/sections since it’s spread out? Would love any suggestions and how you got hold of the gmat quant practice book greg recommended. Thanks so much! For verbal, i only use big book (for time management too) Thank you!
