Need help for improving the verbal score.....

Have you done a diagnostic test to see what portion of verbal you are having the most trouble with? Or are you struggling with verbal as a whole? I did really well in Verbal but I am also a native English speaker, but I can offer you advice with what helped me.

Do a lot of online practice verbal questions. Learn the patterns that the GMAT test makers use. Practice them on a computer. Reading them in a book differs from the actual test environment, so you really need to practice doing the problems on the computer. There are tons of free practice verbal questions on the internet.

In terms of sentence correction, focus on subject + verb + direct object + tense agreement.
Ask yourself:
- Does the subject match up with the rest of the sentence? Example "He are going" is incorrect. "They are going" or "He is going" would be correct
- Does the tense of the verb make sense? Example: "The clock breaks last night" is incorrect "The clock broke last night" is correct
- Does the direct object make sense in the context of the sentence? There will always be a noun for the direct object to refer to. If not, the answer choice is usually wrong! (Sorry if this is confusing. I can't think of how to explain it in simpler terms. But google "direct object" and you can get a better understanding of what I am talking about.)
- Does the tense make sense? "The scientists went to the market tomorrow" is incorrect "The scientists went to the market yesterday" is correct

In terms of the reading comprehension portion, skim the passage to get a general idea of where all of the information is, then read the question and do process of elimination. Pay special attention to whether the question asks "Which one IS NOT" or "Which one REFUTES" or "Which one SUPPORTS". or "Based on the passage, which of the following would the author agree with"

In terms of the critical reasoning portion, write down A B C D E on your scratch paper and cross out the answers that do not fit with the question. It is important to not try and keep track of them in your head because you will confuse yourself.

If you have time, start reading more each day so that your brain gets used to seeing a lot of words and processing a lot of information at a time.

I hope this helps. I took the GMAT 5 times so I know how hard it can be. I struggled with the math section but just try and relax and you will do great!
