TOEFL

For GRE IELTS & TOEFL you won't face any issues, as I've already given 2 of the tests mentioned above I know about the whole process they don't even ask about which college you're studying at, all you need is a valid passport. Talking about MS, yes, there will be hurdles but you can put the final degree as still awaiting.

Hello Geeta,
On this website, you get all the material for CAT or other material for the MBA entrance test. It is a paid website.

Hello Saiteja V, it's very nice to hear from you that you are interested in doing your PG abroad. Admissions there are not based exclusively on academic performance but depends on many other parameters. Hence I would strongly recommend that you should approach an agency that is dealing with sending students abroad for PG. This is so since they would be knowing different aspects to have successful shot at the admission. Best wishes to you.
