The MGMAT tests have a standard deviation of 50 points, so if you were to take the real test very soon, you would have a 2/3 chance of scoring within 50 points (plus or minus) of your last MGMAT test score. The standard deviation on GMATPrep tests is about 30-40 points (the standard deviation of the real test is about 30 points).
The test is not scored based upon percentage correct. It is not the case that a certain number wrong (or right) will get you a certain score. For example, you can get 12 wrong and get a lot of different scores, depending upon the difficulty levels of the questions, the spread of the errors, and other variables.
In terms of improving on verbal, what have you been using so far to improve? What resources have you been using to learn grammar? What about the techniques for CR and RC? It's going to be a matter of diving into those sources, and doing lots of review and analysis, especially when you take a test or do practice problems and find errors or things about which you are uncertain.
Generally speaking, concentrate on either quant or verbal for any particular study session (up to 2 hours). Figure out what you need to review, based upon the data from your most recent practice test, and set up a study schedue to do so. Ask yourself these questions when reviewing a problem:
Was I able to CATEGORIZE this question by topic and subtopic? By process / technique?
Did I make a CONNECTION to previous experience? Or did I have to do it all from scratch?
Did I COMPREHEND the symbols, text, questions, statements, and answer choices?
Did I understand the CONTENT being tested?
Did I choose the best APPROACH?
Did I have the SKILLS to follow through?
Am I comfortable with OTHER STRATEGIES that would have worked, at least partially? How should I have made an educated guess?
Do I understand every TRAP & TRICK that the writer built into the question, including wrong answers?
Have I MASTERED this problem? Could I explain every aspect, fully, to someone else?
How will I RECOGNIZE similar problems in the future?
Also, on verbal, ask yourself:
- why was the wrong answer so tempting? why did it look like it might be right? (be as explicit as possible)
- why was it actually wrong? what specific words indicate that it is wrong and how did I overlook those clues the first time?
- why did the right answer seem wrong? what made it so tempting to cross off the right answer? why were those things actually okay - what was my error in thinking that they were wrong?
- why was it actually right?
