680 - Q51 V28 - Extremely Disappointed

Is your score inline with your GMATPREP scores?
There are many positive experiences shared in this site.
So its not impossible. You have a enviable quant score - some more verbal is required..Buck Up!!

I gave two GMATPreps - one halfway through my prep and another just couple of days before.

In frist I got, 680 - Q50 V31

and in the second one I got 700 - Q49 V35

I am just scared because at the earliest I can give the exam in August first week and then less time would be left for Round 1 applications.

Honestly speaking I am not disappointed with the 680 score but the extremely low 28 verbal score.

Why? Why did you get V28? The closer your answer will be to the truth, the better you can improve your verbal score next time working on your weakest areas.
I agree that 680 isn't bad itself but V28 doesn't sound good to adcoms.

Keep your head up. It does sound like you probably should do a retake with the extreme imbalance, but it's been done before - so all hope is not lost.

Remember the verbal section - is last. So when you transition from quant to verbal - you really need to step back and change your mindset so you are in "verbal mode" quickly. By then, you're probably half exhausted, etc - so just make sure you keep your focus and practice doing so in your studies.

One of our students, Kang, - was in the same boat with a 690 and extreme imbalance. He was waitlisted. But we helped him boost his verbal so his total score was 760. He got off the waitlist and was awarded a $50k MBA scholarship. Now he's at Darden MBA: https://www.gmatpill.com/the-gmat-pill-m ... l-student/

The verbal went from V32 to V41. Now, you're starting at V28 - so you need to bump that up - at least into the mid 30s so your score looks more balanced.
