Hi Sonali,

Yes, of course you can get a good b-school for your mba throught a good cat score.

And also, it doesn't matter if you have taken a 3 year of drop after you graduation for pursuing your masters degree.

All you have to do is only provide a good reasoned affidavit for your droped years at the time of your masters degree admission.

Hope this will help you out.

Good luck.
