Things You Should Be Doing The Summer Before Junior Year

Most students send their first college applications about a month into senior year, with early deadlines on November 1 and some as early as October 15. That means the last full year of grades, classes, and activities an admissions officer will see is junior year, and it starts the week this summer ends. The summer before junior year, the one between 10th and 11th grade, is not when you need to have everything figured out. It’s the time to make a few decisions so junior year doesn’t make them for you.

In this guide, you’ll find why junior year carries so much weight, six things worth doing before it starts, how to choose your classes and your first test, which summer activities actually help, and a month-by-month look at what 11th grade asks of you.

The summer before junior year matters because 11th grade is the year colleges scrutinize most, and this summer is your last chance to set it up with no grades on the line. Junior year is the last full academic year on your transcript when you apply, so it’s where admissions officers look for your strongest coursework, your best grades, and the clearest picture of who you’re becoming. Most of your grades from senior year are sent to colleges after you’ve already applied.

When an admissions officer opens your file, junior year usually answers five questions:

Keep in mind that these questions are answered in context. Many admissions offices read your record against your high school’s profile, and some can see which courses other applicants from your school took, so the question isn’t simply how many Advanced Placement (AP) classes you took, but whether you took the hardest schedule your school made available.

The summer before junior year should cover six things: confirming your 11th-grade schedule, choosing between the SAT and ACT, deciding which activities to deepen, testing an academic or career interest, starting your lists of colleges and summer programs, and building a study routine before school starts.

Each of these is a decision you can make calmly in July that turns into a scramble in October. The sections below take the biggest ones in turn.

Choose the most rigorous junior-year schedule you can do well in, with your hardest classes in the subjects connected to what you want to study. Colleges judge rigor against what your own high school offers, so a student at a school with a handful of AP classes and a student at a school with dozens are held to different expectations.

The classes you take in high school are an important part of any college application. A student who says they want to study medicine, for example, but hasn’t taken biology or chemistry at the highest level available is hard to believe, and so is a future engineer without advanced math and physics. You don’t need to know your major yet, but your 11th-grade classes should point somewhere. Here’s how common interests usually map to junior-year courses:

Rigor only helps if your grades hold up. As Prepory’s CEO Daniel Santos puts it, “GPA alone cannot get you admitted to a school, but it can be the very first thing to cut you out of the pool of applicants that they would even read.” One more AP class is rarely worth a slide in your grades.

If a class you need isn’t offered, or you didn’t qualify for it, the summer is the time to look into dual enrollment, community college, or an accredited online course. Those options can show you’re ready for college work. Admissions officers also know which easy online courses students take to raise a weighted GPA, so take an outside course to fill a real gap in your transcript.

A rough start in 9th or 10th grade doesn’t close doors, and junior year is your best chance to show colleges an upward trend. An upward trend is a pattern of grades that improve over time, especially as classes get harder, and admissions readers treat it as a sign of growing maturity.

Some colleges also recalculate your GPA on their own terms, which can make junior year count even more. The University of California, for example, calculates its GPA only from A-G courses, the college-prep classes it requires across seven subject areas, taken from the summer after 9th grade through the summer after 11th grade, so freshman-year grades never enter that number.

The right plan depends on the student. Some students are better off taking one fewer advanced class to protect their grades, while others should keep their hardest classes in their strongest subject and ease off elsewhere. Working that out with your school counselor, or with a coach through Prepory’s college admissions counseling for 11th graders, is worth doing before the first day of school.

Yes, most students should start SAT or ACT prep the summer before junior year, because the goal is to sit for a first official test by winter break of 11th grade. A fall score shows how far you are from your target while there’s still time for one or two retakes in the spring, and it keeps you from testing in the fall of senior year while you’re also writing college essays.

Start with one full practice test of each. Colleges accept the SAT and ACT equally, so the right test is the one where you score higher and feel more comfortable with the pace. The two tests differ in a few ways that matter for planning:

The Preliminary SAT/National Merit Scholarship Qualifying Test (PSAT/NMSQT), given at schools in October, is the other test on a junior’s fall calendar. Its scores aren’t sent to colleges, but the junior-year PSAT/NMSQT is the qualifying test for the National Merit Scholarship Program, so summer prep can pay off twice.

Don’t plan around test-optional policies yet. Brown, Dartmouth, Harvard, MIT, Penn, and Stanford all require SAT or ACT scores again, and Purdue now expects applicants to submit them. If you want the strongest application, prepare for a test, and treat a test-optional plan as a fallback for students whose scores won’t help after one or two real attempts. The University of California doesn’t consider scores for now, but its Academic Senate is reviewing that policy, so California students should prepare as well.

Focus on the one or two activities you’ve already started and take them further, rather than adding several new ones in 11th grade. Admissions officers look for sustained commitment and leadership earned over time, and by junior year depth almost always counts for more than a longer activity list.

Admissions counselors often talk about a “spike,” meaning one area where a student’s activities go unusually deep. A spike helps, but selective colleges still want to see a life beyond it, like a sport, a job, or responsibilities at home or in your community.

If you want to start something new, start it this summer or in the first weeks of junior year. Something started before Thanksgiving of 11th grade will have about a year of history by the time you apply, which reads as commitment, while something started in the spring is much harder to present that way.

The summer activities that help most before junior year are the ones that either sharpen an academic or career interest or show you contributing to a community. A job, a for-credit course, a research project, a summer program, or a role in a local organization can all qualify, and none of them has to be expensive. Here’s what each common option tends to show an admissions reader:

Whatever you choose, pick something you’d be glad to talk about in an interview a year from now. Admissions officers read a summer as evidence of what you do with free time, and they can tell an interest from a box being checked. For more ideas, see these summer activities that look good on college applications.

The summer before junior year is for setting up 11th grade, and the summer before senior year is for finishing your application. Admissions officers read the second one more closely, because it’s the last stretch of activities on your record before you apply and the time when your college list and essays come together.

Plan that second summer during the fall of junior year because selective programs close early. The Research Science Institute (RSI), a free summer research program for students finishing 11th grade, run by the Center for Excellence in Education, accepts fewer than 2.5% of applicants and closes its application in December, and MIT Introduction to Technology, Engineering, and Science (MITES) Summer closes in early February. For the full plan, see what to do the summer before senior year.

Junior year is busier than many families expect, with testing, summer program applications, and the start of a college list all needed before spring.

By the start of senior year, you’ll want a final list of 10 to 15 colleges and a decision about where, if anywhere, to apply early. Early decision (ED) is a binding plan, meaning you commit to attend if admitted, while early action (EA) gives you an early answer without that commitment. For a more detailed month-by-month version, see Prepory’s college planning checklist for juniors.

Also, the Free Application for Federal Student Aid (FAFSA) uses tax information from two years before the school year it covers, so for most students, the calendar year that includes the summer before junior year is the income year their financial aid will be based on.

The summer before junior year isn’t the summer to impress anyone. It’s the summer to decide which classes you’ll take, which test you’ll prepare for, which activities you’ll lead, and which deadlines arrive before Thanksgiving. Students who start 11th grade with those decisions made spend junior year doing the work instead of catching up to it.
