GRE

Hi,
Check University of Texas at Dallas, John Hopkins University, Indiana University (Kelly), University of Southern California, Boston University, University of Washington-Seattle Campus, Missouri University of Science and Technology, Drexel University and more. On the more competitive side you can check Carnegie Mellon, Georgia Tech, and Virginia Tech etc.

Well, it is depending upon that towards which field or work you want your future to be. It also depends on your eligibility to apply for the university. It can even be a College affiliated with a University.

Number of online test preparation materials and official guides for GRE are available on: http://www.ets.org/gre
Hope this helped.

Hello Anuplab, USA most of the universities require GRE and TOEFL scores. There are few universities who don't require GRE scores, but they are not ranked as such. Whereas in UK, you will have to only go for IELTS exam. GRE is not required for MS. Also USA gives you OPT but UK do not have post study work visa.

Dear Phani,
You seems confused between GRE/GMAT. Before opting to the college, first choose your area of study (after B.Com of course you will not go for engineering so GRE options is close for you as this is for Science and technology), now left is GMAT before choosing exam choose the country and college. And as per their criteria, go ahead. GMAT is just an entrance exam. Actual story starts afterwards. Hope this helps.

Hi Navneet,
For Masters in USA, TOEFL /IELTS is mandatory along with GRE for a majority of the universities for international applicants (those who have or will request a visa) and applicants (including US citizens and US Permanent Residents) whose first language is not English and/or who have not completed a Bachelor degree in the United States.

Yes, you can get admission for MBA through GRE score.
All the best!

If you have academic marks more than 80%, you will get free education in German universities. You have done all required exams, hence you can apply directly. As the procedures are little complication in processing your application and visa, it is better you can do this through education consultants. It is worth paying them service charges for this work.
