Hi Pallavi,

The biggest problem that you will face will be getting rid of the inertia.The best way to deal with it is to start with your strongest section. Do the revision on day 1 and start solving easier questions on first 2 days. This will slowly bring you back in the prep mode and will set the ball rolling.
After this make a time table (a realistic one) and give maximum weightage to your weakest area.Try doing quant for 2 days, verbal for 2 days ...so that in a week you brush up both quant and verbal.
After studying for about 10 days, you will start feeling confident and thats the time to take your first mock.

The important points you should take care of are :
1. Concentrate more on your weak areas.
2. Dont overstress
3. Try solving only official problems.

Eki

Thanks...

Yes an important consideration will be exactly how many days to block for initial practice before taking my first mock...

Since you have not taken any CAT except the GMAT PREP's i would recomend that you spend the initial few days revising the concepts that are tested (refresh your memory). You can use GMAT QP 1 for practice, it has some great questions especially in the Medium-High and High Difficulty areas and is a must do especially if you are writing the test for the second time. You can then move on to take Manhattan tests (free with the purchase of a strategy guide) and see where you fall short (it gives you top class analytics) so that you can plan a targeted prep for the next few weeks.
