GMAT experience, Q49, V22, 600

Hey Folks,
I am sharing my GMAT experience. The test was taken at GMAT centre in Pune, India.
Center name: GATS, Pune
Day: Monday
Date: 7th of Sept, 2020.

I started my preparation in March 2020.
Exam experience:
1. Quant questions were a bit difficult.
2. For GMAT prep tests, I was able to complete the quant within 40min. But in the actual test, questions were lengthy. I was able to complete but given time.
3. Verbal was not a good area for me. I screwed up completely.
4. I got no scientific passage for RC; I was expecting at least one.

Test center experience:
1. Center admin team was very friendly.
2. Unnecessary security checks were not present. one can simply get from the cab and walk directly into the center without any security checks.
3. I found many negative reviews about the GATS centre, as the centre is old compared to other centres in Pune. But, I would say there were no issues found neither in the system not in the sitting area.
4. The test room was quite pleasant. The computer system is decent.
5. Sound insulation is very good.

Please guide me for a retake.
My background:
I completed my Bachelor of Engineering in Mechanical Engineering in 2015. I was searching for a job and preparing for GATE exam to pursue Master of Technology. I started my M.Tech in 2016 with specialization in Solid Mechanics and Design from IIT Kanpur. I am currently working with TATA Motors Ltd. as a senior manager in Engineering Research Center. I am targeting 760 score. Need to get into top 25 FT B schools. Please provide me guidance. I joined Jamboree for classroom coaching. Before joining, I can say because of my engineering background my quant is strong; Quant needs to brushed a bit to get Q50/51. Please guide me for the verbal improvement. As the coaching at jamboree was more or less like basic theoretical. I didn't appeared for any other mock tests like eGMAT, or MGMAT, etc.

Please comment for any specific query.
