The most important criterion for most scholarships is a good academic score, however, it also depends on factors such as your chosen destination, subject, and level. In some scholarships, factors like extracurricular activities, and volunteering can also be used to advantage. Keep in mind that every scholarship has its eligibility criteria. While in some, a mere application may suffice, while for others you may have to fulfil several other conditions. For instance, in research-centric programs, you may have to submit written assignments. Do not hesitate to contact the university admission centre if you have any doubts.
