GRE

Yes Giriraj, GRE scores are accepted and converted to equivalent GMAT scores. You should see websites of the universities you plan to apply to. GMAT is however given more preference.

It seems you are interested in studying USA. For USA you need to clear GRE & TOEFL/ IELTS/PTE exam. On the basis your academic, test score, essays you can fetch scholarships for your study in USA.

no GRE is not necessary for Canada u have to score in IELTS only but u need to score 6.5 in each module 6 minimum or more than that

Some universities may have a requirement for GRE and some may not have. I suggest you to check with the universities for the same.
However, IELTS/TOEFL scores are mandatory to fulfill minimum English language requirement.

yes it is enough. All depends on ur graduation score and TOEFL.

Hi Sauvik,
It's hard to compare, both TPR and Manhattan are quite popular. One way to find out is by visiting the centers and find out the statistics. Try to get in touch with ex and current students. Compare the study materials and the schedule, most importantly are the instructors certified? Diagnostic tests are important, enquire how realistic are the mock tests with the actual tests. Finally it's upto an individual how he deals with competitive tests no matter what. So choose the center as per your suitability.
Hope this helped. Please feel free to revert for any clarification.

Hello Debashis,
There is no minimum requirement for GRE. The exam is taken for Graduate programs abroad. You are required to fill the form online after you create an account or register yourself. The official website is ets.org

While exploring other opportunities abroad, you must make a note of your future plans, your budget, your academic background, language barriers and career opportunities in the country you are applying to. List down pros and cons of each thing and you'll be able to narrow down one destination. Apart from Hong Kong, you can also explore US, Canada, Australia etc.

Hi Anjali,
I would like to know which program are you planning to apply for. GRE is not mandatory in Canadian universities. Although it is going to enhance your admission chances if you plan to take it.
