Experimental Questions Adjustment

Usually, you would not know which questions counted and which did not. In addition, there are other factors at play as well, such as different topics (e.g. testing of geometry vs. probability vs. arithmetic) - you may be better with one of these topics than others and depending on the distribution of questions, you may score higher on one than the other. All of these things including time of day performance and external distractions at the test center (someone sneezing next to you) may add up to a difference of about 40 points. That's the standard error on the GMAT.

You cannot really make out the difference between experimental question and the normal question on the GMAT, hence it is of no use cracking your brain around it.
Since you have just started your preparation, you need not worry much about the score. This an certainly be improved.
Your mock scores shows a clear lack of fundamentals in the Verbal section. In your preparation so far, how did you study? What material did you follow?

1. Did you take the test including AWA and IR?
2. Did you complete both the sections? (There is a high penalty if you do not complete a section)

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

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.
