GMAT Bad experience ... 640.. Need suggestions on Verbal improvement

Dear GMAT Club members,

First of all... Hello to all.

I have taken GMAT 10 days and my score is 640 (Q -50 , V - 26, IR -7 , AWA 4.0). Although this represents my actual level, I would like to increase some 40 to 50 points. Please suggest me on ways to improve the score.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Brief exp of my previous preparation and attempt:

1)I studied for around 3 -4 months.
2)Took the verbal course from egmat , but could only master the SC part.. Even though I completed the remaining parts (RC and CR), I couldn't gain full knowledge of the concepts / application. (Don't get me wrong.. Egmat course is very good ....May be I was not the right fit for the egmat course).
3) In the practice mocks (800 scores, GMAT prep 1,2 ., MGMAT) .. My scores in the verbal fluctuated between 29 and 35.
4) For quant , I didn't take any materials. Went through the GMAT club Quant book and practiced the questions on CAT's and GMAT club.

Exam Day :

1) took the 3rd order ( Q, V, IR and AWA)
2) Quant went good. Don't think I remember making any silly mistakes
3) Verbal ..

Thought that first few questions went good. But took lot of time.. (timing is my main issue in verbal). 3rd RC came relatively late compared to my practice test and little bit lengthy as well. From there , I lost the plot and couldn't concentrate on the accuracy. ( I was just going on.. )

In short.. Verbal went wrong .. and I would accept that there were some concepts gaps and also issue with the application of the known concepts.

I am planning to take the exam again in month of Dec (preferably before 10th ).And also, this is going to be my last time as well. ( i feel like .. GMAT has defeated me)
So I have around 2 months on my hand.
My sole focus this time would be to improve the verbal score ( obviously with out losing the Quant score ). My target score in verbal is 36 ( so that I can get to 700 level). And I want to try the different approach / way this time around. (And also, Egmat subscription is expired ... so anyhow i have to buy a new course for the verbal.)

I read some very good reviews EmpowerGmat , so.. I am thinking of trying their verbal course.
Could you all please provide your feedback on the EmpowerGmat course
