I have kaplan and OG at my disposal. planning to buy manhattan test series as well.
I did take the diagostic test before starting the preparation.
please suggest.
thanks in advance

Any one is ok.

if you take Kaplan, remember that you will score atleast 40 less than ur levels because Kaplan's questions are tougher than other test prep companies.

The Manhattan tests are pretty good, and so are the GMATPrep tests. If you think you're still going to make a fair amount of improvement after this first test you can take the GMATPrep test first. However, if you don't think you're going to move you score up too much you may want to save the GMATPrep test for later and just use a Manhattan test to start with.
