What to practice and what to leave from the GRE Big Book

Hi all! I’m currently using the GRE Big Book for my prep but want to avoid wasting time on outdated material. Can anyone clarify exactly which question types (like Analogies or Logic Games) I should completely skip, and which ones are still relevant for the current exam format? I’d love to know the most efficient way to use it for both Quant and Verbal. Thanks!

I have done so far 2 tests of the big book and I am excluding all analytical sessions plus questions 8-16 and 28-38 of verbal sessions.

However, at this point I realized I have not seen a single question with factorials and this made me leave the big book for a while and concentrate on Greg mat quant exercises and the official guide to simulate more realistically the real current gre test. This is my next step.
