Senior year starts and suddenly everyone around you is talking in acronyms. Your school counselor mentions ED. Your older cousin says she applied REA. Someone in your friend group got deferred and is now drafting a LOCI. You nod along and then go home and Google everything separately.
This is that blog. All the terms explained in one place.
The Application Plans, Actually Explained
Early Decision (ED)
This is the one that trips people up the most because of the word "binding." What it means practically: you apply in November, hear back in December, and if you get in, that is where you are going. You pull all your other applications. There is a signed agreement involved. It is not optional.
Why do colleges do this? Because colleges love guaranteed enrollments, and they reward ED applicants with significantly higher acceptance rates at most schools. The gap between ED and regular decision rates can be enormous for some colleges, sometimes 30 to 50 percentage points. That advantage is real.
The downside is just as real. You accept before seeing financial aid offers from anywhere else. If you need to compare packages, ED is not the right move. Find more on Early Decision here.
Early Decision II
This is the same as ED but with a January deadline instead of November. Same binding commitment, but a slightly lower advantage over regular decision, useful if you were not ready in November or got deferred from your first choice. Decisions usually come in February.
Early Action (EA)
This lets you apply early and hear back early without committing to anything. You can apply EA to as many schools as you want and still say no if you get in. Georgia Tech, MIT, and the University of Michigan are among the more well-known EA schools. No pressure, just earlier information.
Restrictive Early Action (REA) and Single-Choice Early Action (SCEA)
REA and SCEA are the same thing with different names depending on the school. Non-binding like regular EA, but with one restriction attached: while your application is pending, you cannot apply early to any other private school. Public universities are fine. Regular decision applications elsewhere are fine. Just not EA or ED at another private school simultaneously.
Harvard, Princeton, Yale, and Stanford all use this model. Read the specific policy for whichever school you are applying to, because the exact wording on what is and is not allowed varies slightly between them.
Regular Decision (RD)
This is what most people do. Apply by January 1 or so, hear back in late March, decide by May 1. You can apply to as many schools as you want and compare every offer before committing to any of them. The pool is larger and more competitive than early rounds, but you have full flexibility on cost and choice.

Rolling Admissions
Some schools, mainly large public universities, review applications as they arrive and send decisions back within a few weeks year-round, until the class fills up. Applying early in a rolling cycle matters because spots and scholarships fill over time, even if there is technically no deadline yet.
What the Decision Letter Actually Says
A deferral is not a rejection. If you apply early and the admissions office is not ready to make a call either way, they move your file into the regular decision pool. You still have a real shot. You can send a letter of continued interest with any meaningful updates, a stronger grade, a new achievement, and it can genuinely help. The key distinction: a deferral happens in December when most seats are still open.
Being waitlisted is different. That happens in spring, after the class is essentially built. If enough admitted students decline by May 1, spots open up and schools pull from the waitlist. Some years that happens for hundreds of students. Other years barely anyone moves. You will not know which kind of year it is until well after May 1, so commit a deposit somewhere you actually want to go in the meantime. Being deferred is the better position of the two.
The Academic Terms Worth Knowing
Weighted vs. Unweighted GPA
This comes up constantly and confuses people more than it should. Unweighted is the standard 4.0 scale where every A is a 4.0 regardless of the course. Weighted gives extra points for harder classes, so an A in AP Calculus might count as a 5.0.
Most colleges recalculate your GPA their own way when reviewing your file anyway, so the number itself matters less than the transcript showing you took challenging courses and did well in them.
How Admissions Actually Works
Holistic admissions
This means the school looks at more than grades and scores. Essays, recommendations, what you have done outside school, your personal circumstances. Most selective colleges use this approach, which is why two students with identical numbers can get different outcomes. There is no single formula.
Demonstrated interest
DI refers to whether a school can tell you actually want to go there. Campus visits, attending info sessions, emailing admissions, opening their emails, alumni interviews. Some schools track all of this carefully. Others do not care at all. The way to find out which kind of school you are dealing with is to look at their Common Data Set, search "[school name] Common Data Set," and find the section on how they weigh admissions factors. It will tell you directly.
The Platforms and Terms You Will Use Daily
The Common Application
This usually just called the Common App, is the platform most US colleges use to receive applications. You fill out one profile and send it to multiple schools from the same place. Over 1,000 colleges accept it. A handful of schools use their own systems instead.
First-generation College Student
A first-generation college student is someone whose parents did not complete a four-year college degree. Many colleges actively recruit first-gen students and offer dedicated scholarships, mentorship programs, and support resources specifically for them. It is not a disadvantage to identify this way on an application.

FAQs/PAA
Q: Can I apply ED somewhere and EA somewhere else?
A: Usually yes. Not if either school uses REA or SCEA. If you are applying to Harvard, Princeton, Yale, or Stanford early, you cannot apply early to any other private school at the same time.
Q: Does demonstrated interest actually move the needle?
A: At schools that track it, yes. At schools that do not, no. Check the Common Data Set for each school on your list. It will tell you how much weight they give to applicant interest.
Q: I need financial aid. Should I still apply ED?
A: Only if you have already used the school's net price calculator and you are comfortable with a likely aid package without being able to compare it against other schools. Otherwise, regular decision gives you leverage ED does not.
Q: What is the Common Data Set?
A: A public document every accredited US college publishes each year. It has acceptance rates, financial aid figures, and admissions factor weightings. Search the school name plus "Common Data Set" and you will find it.
