Hey there I am glad to help you out i hope this helps you

I wish to clarify a few things first before I start answering your question.

MCA is a very India specific thing. This course will not be found anywhere else in the world but India.

You can although do a MS (Master of Science) in Computer Sciences abroad. MS is usually a 2 year course (but there are a couple of university’s in UK & Australia that offer a 1 Year MS also).

Also please note, that the eligibility requirement for the MS course will be 12+4 = 16 years of education. In your case, since you have done your BCA you have only 12+3 = 15 years of education. You will need to do 1 year of MCA or MSc to even be eligible for admission to MS courses abroad.

If you do manage to do that, then you will have the following to do’s

US Colleges

TOEFL - Test of english as a foreign Language - required for MS in USA

GRE - Graduate Record Exam - Computer Based aptitude test which has sections in Vocabulary, Quantitative & Analytical Essay.

UK & Australian Colleges

You will need to give the IELTS exam (its similar to TOEFL)

apply for Scholarships abroad in countries like UK, US, Canada, Australia, New Zealand, submitting your academic record right from SSC and upto BCA degree, and extra curricular activities like games, sports, debates, community service, blood donation,environmental protection etc, prizes,awards obtained etc. You will get the financial support based on your excellence of your biodata.Then you choose the university and the country for higher studies. You also apply for Passport and driving licences and keep them ready as they serve as additional supportive documents to further your chances to go abroad for higher studies.
