Recently, in our group we had one of our friends who went to US for his higher education. We all supported him to get the best knowledge about the entrance exams & procedures to take admission in a US University. Well I have a resource i.e. a guide may be you’d like to have a look upon. It’s an online guide, I can give you it’s URL which is link it’ll help your brother get the best in preparations for his abroad studies. It’s expensive, but it’ll tell him exactly what to do for admission in top colleges.
