Hi Ashandilya,
I am sorry that the test day did not go as planned and it is good that you have identified some issues.
Before I give any advice, it would be helpful if you provide me the answers to the following questions:
1. Did you take the mock CATs including the AWA and IR sections?
2. Did you solve all the problems from the OG and the Verbal Review?
3. Did you complete both the sections? (There is a high penalty if you do not complete a section)
4. Did you go through all the concepts in the course?
5. What were your sectional scores?
You need to build the concepts/fundamentals before you jump in solving the problems. You can do so by choosing one of the following ways:
1. In person classes/private tutoring
2. Online classes
3. Self paced online preparatory course
4. Book heavy approach
Since you have already studied by using a book heavy approach, I would urge you to change your strategy. Most of the preparatory companies including ours offer a free trial of our course. You can take the trial and see if the course suits your needs.
Our course comes with a 50 pint of money back guarantee to and this shows our confidence in your course.
In addition to the preparatory material, buy the Official Guides(both the Official Guide and the Verbal Review), Question Pack 1 and the 4 official mock CATs. They should be an indispensable part of your preparation.
You need close to 3 months to prepare well for the GMAT.
1. Understand the concepts and fundamentals before jumping into problem solving
2. Solve full length CATs including AWA and IR. You can get two free GMAT Prep mock CATs and can purchase two more from mba.com
3. Make sure you solve the official questions from the Official Guide
