Hi auj012,
Your mock score shows a clear lack of fundamentals.
1. Did you take the test including AWA and IR?
Also, I would recommend you to refrain from taking tests until you have gone through all the fundamentals.
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
You can either go back to the course that you have attended and revise the concepts or opt for a new course. Most of the preparatory companies including ours offer a free trial of the course. You can take the trial and see if the course suits your needs.
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
4. You need to be focused and follow a plan. Try to put in 2 hours atleast on the weekdays and 4 - 5 hours on the weekends.
5. Thoroughly analyze any mock CAT that you attempt and see which questions you could have answered correctly.
