After completing 11th grade, you should start your college application. The first step is to compile your college list. Research well on which universities give scholarships for international students. After determining your best fit colleges, label them as safety(high chance of admission), target(likely), and reach(hard to get admitted) schools. Work separately for each school on your list. Since most colleges require standardised test scores, you should take either the SAT or the ACT. If you are aiming for a fully funded scholarship, you need to score high on these tests (preferably above 1400 on the SAT and the ACT equivalent). The higher your score, the better your chances. Your next step is to provide your English language proficiency through the TOEFL or IELTS exams. Some colleges might accept the Duolingo English Test; check the college's website to see their requirement. It is essential that you have adequate extracurriculars too in order to strengthen your chances. These include active participation in your school clubs, volunteer activities, or any other ways to demonstrate your leadership skills. Personal essays are also key factors to determine your eligibility. Plan your essays ahead(a month before the deadline is advised) and proofread before submitting. Since your essays are the most important factors in scholarship eligibility, it is to your advantage to spend adequate time on them. Finally, ask your teachers(preferably from core academic subjects) to write recommendation letters for you. Good luck.
