If all other external factors truly are equal, then basing your decision on scholarship money is not the worst decision you could make.
However, everybody's personal situation is a bit different. For instance, do you have a spouse or kids to consider? How about the distance you live away from family at one school compared to another? Where do you think you will be challenged the most academically? Which school do you think will give you the greatest opportunities to thrive, personally, academically, and professionally? What does each city/school offer in terms of extracurricular activities away from studying? Where did you feel the most comfortable during interviews? Are these scholarships renewable? If so, what is the criteria? - GPA, being in the top X% of your class? What does your gut feeling tell you to do?
These are just a few items off the top of my head. If in all honesty these factors are truly equal to each other across the board, then choose the school you will attend based upon criteria that matters to you. If this criteria ends up being scholarship money, then it ends up being scholarship money. In the end, commit yourself to a school according what matters most to you, be happy with your decision and don't waste time second-guessing yourself or else you'll always wonder 'what if'. Hope this helps. Best of luck!🙂
