Hi
Rawbs,
Welcome to GMATClub.
It a very realistic goal to begin with, but is going to take some consistent effort to reach your goal score of 680.
I have a few recommendations for you :
1. Once you begin with the preparation for GMAT, clear your concepts for every topic and immediately
follow it up with some practice. To build your concepts, you could use eGMAT which is well scripted
in the form of videos explaining each topic.
2. Coming to the Verbal Section,
eGMAT it is the best source available for Sentence Correction. Use the practice questions and
work on the Official Guide side by side to understand if the process is working for you or not.
There is no easy route to achieving a high accuracy in CR and RC, except extensive practice.
You could use the PowerScore CR bible(as an additional source) in order to reinforce your concepts
once you have completed the concepts in CR using eGMAT.
For RC, this link is very beneficial:
https://gmatclub.com/forum/gmat-club-s- ... 83101.html3.For the Quant Section, Follow Bunuel at the Math Forum
His signature contains some awesome questions that give you the true taste of GMAT
(Baker's Dozen, 12 Easy Pieces etc..)
Make sure you solve each and every question he puts up on the forum.
What I think is very important for you or anybody preparing for the GMAT is to stick to your schedule
religiously and not miss a single day.
Hope this helps you!
