In many cases, study abroad scholarships are given by the universities to students with a very strong profile that is on merit. In most cases students are considered for scholarships when they apply to the university. They are given scholarships based on their academic performance, statement of purpose, recommendation letters, extracurricular activities and any other factor that could be unique to their profile. In some cases universities can ask for essays. I think you should first decide where to study, it is a very generic query on the whole. Research on countries and universities abroad, the fees, eligibility etc. And make some sensible choices depending on your profile and budget criteria etc.
