Ok. I suspect this is why your score is too low.

The penalty for leaving questions unanswered is far higher than getting questions wrong.
It is an absolute must to complete all the questions in the test. See below post regarding how scoring works in GMAT.

The score depends on a lot of factors not only the number of questions that you mark correctly.

As you mentioned that You did not attempt 6 questions, that affects your score negatively.
In addition if you have mistakes consistently, then the difficulty level of the questions does not increase.
I would recommend you to appear for another test and see how you fare.

How are you preparing for the GMAT?
What preparatory course/book are you following?
Have you solved the OG?

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

Whatever you choose, make sure that you choose one. Because GMAT tests you on some concepts and fundamentals that you can learn from a course. 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.

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
