Okay, I’ll take a stab at this.
As the ACT is thought to be more of a “curriculum based test” than the SAT, a student with an unweighted 4.0 GPA should be scoring in the 34, 35 and 36 range. Why is your ACT not in sync with your GPA? That’s probably the first question an Admissions Officer is going to ask. Does your high school have grade inflation? Does your family (a Harvard alumni family) lack the financial resources for you to take a test prep class? Or, does your family lack the resources for you to retake the ACT again and again to improve your score? Is English not your first language? Do you have test anxiety? Why are you not scoring higher? All of those questions will occur to an AO within the first 5 seconds of looking at your test score. In fact, if you submit both ACT test scores, an Admissions may start to question MORE why your test scores are out of sync with your GPA. So, I would only submit your best composite score.
From there, an Admissions Officer will look over your profile and see that, on paper, you resemble several thousand other applicants – even with the parkour (you underestimate how many teenagers are interested in parkour). What differentiates you from the rest of the crowd? They’ll dig a big deeper and look to see what your recommendation writers say about you. Are you the brightest student this teacher has taught in their career? Do you contribute to the classroom conversation? Is your hand always raised with thought provoking opinions and questions? Are you respected by your teachers? Do you inspire your classmates to work harder? Do your teachers think of you as a role model for your peers? Do you “shine the light” that others follow?
Beyond those questions, they’ll look to your guidance counselor’s Secondary School Report (SSR) to see how you compare to the average college bound student at your high school. Were there any extenuating circumstances? What did the faculty say about you in private conversations? Did you materially participate in the extracurricular activities you noted on the Common Application? Did you take the most demanding course load available to you at your high school?
Then, an Admissions Officer will look toward your essay. Of all the topics you could have chosen, what did you choose to write about? Are you mature? Thoughtful? Tolerant of other people’s belief’s? Would you make a good roommate? Would you inspire your classmates to greatness outside of the classroom?
Lastly, an Admissions Officer will look toward the interview report for a clue to your character. Did you look the interviewer in the eye? Did you have a firm handshake? Were you confident? Were you cocky? Could you carry on a conversation about current events? Past events? What was the last book you read outside of a classroom that inspired you? What do you consider your greatest weakness? What do you envy most in other people? What would your worst enemy say about you? What would your best friend say about you?
All of that information will go into the hopper and ultimately will become the basis if your file brought to the attention of the full Admissions Committee (not very student makes it to the full committee – only those students who the regional admissions director feels can garner the support of more than 51% of the committee are presented). In comparison to all other applicants, is that you?
As you can see, so much more than the statistics presented above goes into the decision. Bottom line: There’s too much unknown information that could tip the balance. You just have to send your application out into the universe and see what happens. Best of luck to you!
