Stuck at 710-720, V35-37, for the past two years. Urgent help needed.

Hi,
Yesterday I took Gmat for the 5th time and scored 710. My last few scores have been

710 Q50, V35 Sep'16

Anybody in my place would understand the frustration and disappointment I'm going through after repeated failures in Verbal. I just can't solve the puzzle. I have probably tried everything. I have solved almost all the official questions multiple times. Exhausted all the mock series available whether official or from gmat prep companies. I'm so burnt up right now that I just don't know what to do. I have even tried GRE and LSAT material to fix my RC and CR.

Here are some of the problems that I think I'm facing.

* SC has always been my strong point. But in the last two attempts, I'm finding it difficult as I'm averaging more than 90 sec per question and not getting more than V40.

* CR: I think this is still on control now but I consistently take more than 2 mins.

* RC: this is also in control now but again I take over two mins per question.

From the last few ESRs, I have also observed that in the last 10 questions my accuracy levels are less than 50%, prolly because overall I end up spending too much time that for the last 10 questions I get 15-16 mins.

Another problem that probably worked against me is that I took less mocks. Overall this year I prepared for 6 months but took only 6-7 mocks. This is again because I have exhausted most that are available out there.

Another problem is nerves. Throughput the test, I could feel my heart pumping really fast as if I'm doing some cardio workout. And in the last 10 question, it gets even worse. A related problem this past week had been a lack of sleep. I study at night but overtime my schedule shifted from sleeping 4 in the morning to 7-8 in the morning and fixing my sleep time led to lack of sleep in the last week. I think I averaged only 4 hrs during this past week. I hardly get adequate sleep the night before the exam but this time the lack of sleep extended for more than a week.

Before anybody suggests that 720 is a good score and I should apply, I want to mention that in 2014 I applied to 7 schools and ended up getting wait listed by just one school and rejected by others. None of the schools I applied to ranks in top 10. I'm an Indian IT male so I come from a very competitive group. My profile is decent but nothing extra ordinary. So nothing less than a 750 can help me get an admit in a decent MBA program.

Another thing I would like to mention here is that I have never been able to fully justify myself about why I want to do MBA? From the heart, I'm a geek and love to tinker with technology. I dream of building a technology company. So my main motivation is to become a tech entrepreneur. So every now and then I play with ideas and than back out from working seriously on most of them. I just feel that during MBA, I can have time, people, network, resources to build something successful. But we all know that one can do all this without MBA. I also feel that I need to have a bigger view and find the role of a product manager as much appealing as of an entrepreneur. So somewhere there is an ambivalence about MBA. Sometimes I say to myself that it is good to have one then other times I feel so excited about ideas that I just don't want to do anything else but to work on those ideas.

Right now, I'm looking for suggestions about what is the best way forward. I'm totally lost and have lost a lot of valuable years of my life because of indecision and lack of clarity. I'm feeling very reluctant to apply with the same score again, but if I don't that I will lose R1. Or should I try again? What should my study plan in that case? Would a personal tutor help?

I would request experts to please pitch in.
