I noticed that gregmat’s verbal problems section does not have Reading Comprehension questions available. Which test prep material is good as a substitution? To practice easy to medium questions RC.
Feel free to utilize the Official GRE Guides or the Timed Verbal Sections on the GregMat website. In addition, the Big Book can be useful for practice. Also, feel free to take advantage of the Skill Building exercises on the website to iron out any weaknesses.
