<p>Double major in 1 year and 1 summer???
That is not what impressive would mean in an AMERICAN EDUCATION.
Universities know the amount of time and work required by students to graduate within 3 to 4 years, so to graduate in 1 year and 1 summer might not serve the applicant well especially if they are very young and applying to Grad school.
If you read graduate school thread on here, you will find various instances where applicants were denied for being too young even with EXCELLENT GRADES &TEST SCORES, most of them made it through high-school/home-school in very fewer years, and rushed through college as-well; some with the combination of several online classes - but Grad school advice them to take 2 or more years off: travel the world, find a job and get some “REAL LIFE EXPERIENCE” before graduate school. The same was not the case for applicants who took the required amount of time to graduate from college and at-least 20 or 21 years old at the time of graduation.
So this might as well be one of those times where finishing first especially under 3 years might not serve one well. WORK-HARD, follow the program plan and use extra-time to volunteer, join clubs and organizations and participate in sports etc.</p>
