If you think you need to memorize a list of 2,000 SAT vocab words you found on the internet, stop right there. We're about to save you a lot of time while delivering the same results.

In 2005, I applied to college and got into every school I applied to, including Harvard, Princeton, Stanford, and MIT. I decided to attend Harvard.

In this guide, I’ll show you the entire college application that got me into Harvard - page by page, word for word.

In my complete analysis, I'll take you through my Common Application, Harvard supplemental application, personal statements and essays, extracurricular activities, teachers' letters of recommendation, counselor recommendation, complete high school transcript, and more. I’ll also give you in-depth commentary on every part of my application.

To my knowledge, a college application analysis like this has never been done before. This is the application guide I wished I had when I was in high school.

If you’re applying to top schools like the Ivy Leagues, you’ll see firsthand what a successful application to Harvard and Princeton looks like. You’ll learn the strategies I used to build a compelling application. You’ll see what items were critical in getting me admitted, and what didn’t end up helping much at all.

Reading this guide from beginning to end will be well worth your time - you might completely change your college application strategy as a result. 

On the 4.0 scale, an unweighted 4.0 GPA means perfection. You need straight As in every class—not even one A- is allowed. In college applications, this carries a lot of weight. You’re essentially telling the college, “High school classes are a cinch. I’ve taken a tough course load, and I’m more than prepared for what college has to throw at me.”

In high school, I got a 4.0 GPA with a course load featuring 10 AP courses. I got straight As and 12 A+'s. This strong course load, along with a strong application, got me into Harvard and every college I applied to.

While it's flattering to say, "Well, Allen's just a smart guy," in reality I relied a lot more on high-level strategy and effective academic habits. These were the same strategies I applied to my undergraduate work at Harvard and that led me to graduate summa cum laude with a 3.95 GPA. This is the guide I wish I had my freshman year of high school.

Most of the advice out there about how to get a perfect score come from people who didn't get perfect scores. In this exclusive article, I'll be breaking down exactly what it takes, and the ruthless techniques I used to get a perfect score.

In March 2016, the SAT underwent a massive redesign, part of which included a change to its scoring system: it shifted from a 2400-point scale to a 1600-point scale. But how do you compare a new SAT score with one on the old SAT 2400 scale?
