It goes without saying that the best thing you can do here, is to work as hard as you can and earn a good score in order to help your chances of getting into a top school abroad. If you haven’t got great scores, you could always try to compensate these with great SAT and GRE scores.
As schools look at more than academics when considering your application, you can always ensure that you pay attention to the following areas:
Co-curricular activities. Develop co-curricular activities to add color to your personality.
Take initiatives. Get out of your comfort zone and do something meaningful. It could be anything, from playing a sport to organizing a blood donation drive in your neighborhood. Be visible in what you do, rather than a participant that isn’t very interested in what they’re doing.
Personal attributes schools would love to know about include your leadership attributes and your ability to work in a team.
You won’t be able to fake these attributes and skills, so start early and cultivate them. You should pay special importance to improving your communication skills.
