Verbal is hard to do inherently. There are just so many ways you can go with it that unless you have a fundamentally strong understanding of English, it's very very hard. That's where all the guides come in handy, like

MGMAT, Kaplan, and
GMAT Club tests (among others) along with
the Official Guide 12 and its predecessors (
OG 11 is very similar in overlap,
OG 10 has almost none).

Hope that helps!
