Hello Omkar. I would suggest that you could start reading editorials of quality newspapers. This will improve your understanding ability, and would help in verbal section. You can download app regarding editorials from play store, and can read them during office hours(sneak) or even during small breaks. For logic and DI section, I would suggest you to start solving sudoku and kakuro. These games will help you immensely in the lrdi section. For quant section, you can prepare after office hours.

Ideally, you should also take mock tests every weekend and see where you stand, and then plan accordingly for next week.

All the best.
