Study Abroad

It depends on what you plan to study at college.
There is no single University which is best in all fields. Different Universities have their strengths and drawbacks. For instance, in research, Massachusetts Institute of Technology (MIT) is considered the leader but in engineering some would prefer California Institute of Technology (CalTech) or Stanford over any other. For MBA, some students would prefer Harvard Business School while others will go to Wharton School of Business. One side doesn't fit all in the field of admissions. You need to understand "fit". Which college is ideal for you? Which college will help you be successful in life? You will grow the best in which kind of environment? Should you go to a small college with more focused resources or go to a huge Universities with better facilities? All these factors should be considered before applying to college just on the basis of rankings.
