i worked out only official guide 13th edition , when i attempted gmatprep i got a score of 610. I feel i need more exposure to difficulty question both in Q&V. Even though i managed difficult questions reasonably in gmatprep, which i did not expect. If i choose the right materials which can expose me to difficult questions i am confident i can score better. I feel i need to improve in quant topics inequalities,permutation&combination & probability. and in verbal difficult RC'S.please suggest me materials i have 30 days to work on.
If you're interested in honing your skills in a few target areas (e.g., inequalities, permutations & combinations, and probability) we happen to have separate lesson modules on all of these topics (and more): https://www.gmatprepnow.com
We also have a free set of videos that cover Reading Comprehension strategies: https://www.gmatprepnow.com/module/gmat- ... prehension
