I have come across numerous threads here at GMAT Club prescribing books, downloads and time-saving tricks. Accordingly, I have been solving questions from books like the Official Guide, Kaplan 800, Powerscore (in that order). However, my scores have not improved too much with each new set of questions; they remain stuck at around 63-67% (Verbal) or 70-75% (Quantitative).
What step do you suggest next? Should I go back to re-solving the books I have already solved, or should I look for new problem sets?
The essential question is:
how many times do you need to solve the questions in a book? Do you keep practicing the same old till you get them all right, or do you just jump on to a fresh set of books each time? I'm not sure if this is a weird question, or if this is the right platform to ask it, but I guess I had to try.
