I don't see an issue other than you wasting your time and making a pdf (kudos but still)
I think you can easily climb to a 700+
Your target score must definitely depend on the B-school that you want to get into.
A 740 is definitely an achievable score.
Trust me- Indian to Indian
GMAT is predictable
Just use official materials or LSAT material (both available on GMAT Club) for preparing
RCs have a pattern
CR even more so
SC is masterable, if you took classes at Jamboree, and have a good grasp on common english (e.g If you think that " I didn't knew" has no grammar error, then you might wanna brush up on your grammar) Usually on GMAT 80% Questions of SC can be solved purely by Grammar, E-gmat has great ideas for SC but going after meaning wastes a lot of my time
Check out the videos that Jamboree has uploaded on their youtube channel that will help in RC strategy, there's more but why pay, if you can get the context.
I took Manhattan, Jamboree, EmpowerGMAT and some other courses
You must stick to the official material, such as old paper based tests (available on GMAT CLub)
New advanced questions
New OGs
The question pack on mba.com
Everything official
Jamboree has a blue book that I did, it had all the past present and other questions, official ones of course
Their website has it in digital quiz format.
But so does GMAT Club
LSAT RCs can help you a lot, I was so proficient in RC by the time I took GMAT that back then I could just tell what the predictable trap they are trying to make me fall into is
Everything is available on GMAT club, just don't go for anything unofficial, because I truly can feel the difference between the actual GMAC questions and the other services
LSAT questions can be easily found in Question banks on GMAT CLUB
