Hi,
If you're planning to take the test within a month, I'd recommend the following strategy:
1. Write a prep test to zero in on three areas in quant and verbal in which you are the weakest/least comfortable.
2. Work on those areas for a weak.
3. Write the second prep test to see if you have improved on those areas. If yes, then find two areas in which you are the weakest/least comfortable. If your improvement in the areas diagnosed in step 1 is less then desirable, then continue working on those areas. Give yourself 4 days for this step. (Now you're on day 11)
4. Write the third prep test. By now, you would have strengthened your weak areas to a good extent. If not, work on them for another 4 days. If your comfort level in areas diagnosed in step 1 and 3, then it's time to work on your time management. Read some of the time management strategies at the GMAT club. It would help you a lot. Practice your time management skills by doing problems from the
OG. Take 4 days for this (Now you're on day 15)
5. Write the 4th prep test to see if you are able to implement the time management strategies effectively. If not, work on it for 5 days. (Now you're on day 20)
6. Write the 5th prep test and analyze your performance and work on some weak areas which you may have skipped for another 3 days. (Day 23 it is)
7.Write the 6th and last prep test to see if you have overlooked any particular area. If not, then use the next 3 days to revise what you have learned over the past few weeks. If you feel you need a little more practice on some areas, hit the books and do problems. (Day 27)
8. Last 3 days, use it to prepare for the AWA... You can also use this time to calm your nerves and mentally prepare yourself for the test.
