Hi Kashif, Welcome to gmat club!!
I think you have made a good decision to order
MGMAT bundle. I hope you have ordered the
MGMAT complete set with three official guides, as OG is mandatory for a good practice. In my personal opinion, I think
MGMAT guides are sufficient enough to help you getting your 700 mark. One additional resource for getting a high Q score is
gmat club tests, but you have to take your Q score to 46-47 before taking these tests.
After going through the
MGMAt guides you will feel the difference. It definitely helps in improving your skills.
Best of luck & keep us posted!!
