Hi Amit700,
Since you're not planning to retake the GMAT until the end of February (and your application deadlines are not until March), you still have plenty of time to study and improve. That having been said, since you have just a little more than 3 months of potential study time, you will have to be really efficient with your studies going forward. If you want to finish the resources that you are currently using, then that might be fine - but the type of Score improvement that are after will require that you make significant changes to how you 'see' (and respond to) BOTH the Quant and Verbal sections - and it is not clear how you are going to do that if you're simply working through more practice materials in the same ways that you worked through previous materials.
You might consider taking a NEW practice CAT/mock this weekend (or sometime shortly after that) so that we can see if you are making any substantive changes to your Test-taking routine. Once you have your next CAT Score, you should post back here (or you can feel free to PM me directly) and we can discuss the results and how you might best proceed with your studies.
GMAT assassins aren't born, they're made,
