Advice on the prep for the last 10 days

My exam is in 10 days, i am in the middle of week 6 of 2 month plan. I am still struggling on the verbal part, I gave powerprep 1 20 days ago when i was in week 4 and the score was 170Q, 156V. Now that i am doing bigbook RC, on each section there is 2-3 mistakes, I am worried about my verbal in total.

What should i do to maximize my output and preparation in these 10 days?
