Microsoft Learning has a tool to help you locate instructor led training resources in your area. Here is the link:

I am seeing at least three training centers near Bangalore.
In addition to instructor led training, there are also eLearning courses, practice exams and a MS Press training kit book. Here is the link to the Microsoft Learning web page that shows details about preparing for this exam:
