Hi sanity,

You have not provided your sectional breakups, anyway thats not an issue.
Please identify your weakness areas in both quans & verbal.
Say, if you are not scoring well DS and your hit ratio is lesser than expected level, practice more DS questions.
Practice until you feel like your hit ratio is improved during your practice.
Try to do the same approach for all of your weakness area in both quans & verbal.

If you feel like the materials you have are not enough to give you good practice, you can try solving the problems listed in beatthegmat.

Hope this helps.

Thanks,
Kalyan.
