My advice to you would be practice, practice, and more practice.
Manhattan SC book is a great one to improve SCPowerscore Critical Reasoning Bible
is a great one for CR
OG Review and Verbal Review are good for Verbal and you must have those.
RC sometimes have patterns too. For example, when an article present old view and new view, the topic sentence or the main idea is almost always around the new view. When dealing with minority article, the author's tone will never be negative or extremely critical.
Verbal is my weakness as well. I started out with a low 15V score that I am still too shamed to share it. But now I can almost always score 35V on most of the CAT I took. I have less than a month for my real exam. My target would be 40V.
dont be ashamed.
i purposely didnt take a practice exam because i knew it was going to be low. i started from the ground up and i am slowly building my knowledge base. should be done by december. haha
