Hello Sankruti,
This is what I think must be your study plan till you take your test.
When it comes to material, remember that anything that is NOT official is NOT reliable and hence the GMAT Prep tests must be the backbone of your preparation. This is how you can space the 4 tests that GMAT gives you.
GMAT Prep test 1
Cover all the basics. This can be from the
OG, VR and QR.
GMAT Prep test 2
Now practice using questions. You will solve questions from
OG, VR, QR and the Test prep pack that GMAC has to give.
GMAT Prep Test 3
Analyse all these three tests and come up with top 3 problem areas each in SC, CR, RC and Quant. WOrk on them.
GMAT Prep test 4
Now just start refining your weakness areas and keep working on them.
Some other things that you might want to note in addition to the above.
1. You can use any other test series if you have already taken the GMAT Prep tests ( Nothing can beat them though)
2. Between every test make sure that there is atleast one thing that you have learnt.
3. Make sure you fix on time - 8 questions and 15 minutes.
4. Ensure that you analyse your tests well. Analysis should include the reason why you got that question wrong - You must also be confident enough that you will NOT repeat the same error again.
Hope that helps.
All the best
