Glossary & Sources
Every word explained simply, plus where every number comes from.
Here is a friendly dictionary for this whole site. If a word ever looks new, find it here and keep going. None of it is as complicated as it sounds.
Academics
- GPA
- Grade point average: the single number that summarizes your grades.
- Unweighted GPA
- Grades on a 4.0 scale where an A is 4.0, no matter how hard the class was.
- Weighted GPA
- GPA that gives extra points for harder classes (honors, AP, IB), so it can go above 4.0.
- Course rigor
- How challenging your classes are. Colleges look at whether you took the hardest courses your school offers.
- AP (Advanced Placement)
- College-level high school courses with an exam; a strong score can earn college credit and raises your weighted GPA.
- IB (International Baccalaureate)
- A rigorous international program some high schools offer instead of, or alongside, AP.
- Honors classes
- Advanced versions of standard classes, harder than regular but usually below AP/IB level.
Testing
- SAT
- A standardized college admissions test scored 400 to 1600. Now fully digital and adaptive.
- ACT
- A standardized college admissions test scored 1 to 36. The new 'Enhanced ACT' makes Science optional.
- PSAT 10
- A practice SAT taken in 10th grade. Low stakes, good for a baseline.
- PSAT/NMSQT
- The junior-fall PSAT that qualifies you for National Merit Scholarships.
- National Merit
- A scholarship program; high PSAT/NMSQT scorers earn recognition and can win awards.
- Superscore
- Combining your best section scores across multiple test dates into one higher total.
- Test-optional
- A school lets you choose whether to submit SAT/ACT scores. Submit only if your score helps you.
- Test-blind
- A school will not look at SAT/ACT scores at all, even if you send them. The entire UC system is test-blind.
Admissions
- Academic Index
- A quick combined score of your GPA, course rigor, and test scores that top schools use to screen applicants.
- Holistic admissions
- Reviewing the whole applicant (grades, activities, essays, context), not just the numbers.
- Early Decision (ED)
- Apply early with a binding promise to attend if admitted. Often a meaningfully higher admit rate.
- Early Action (EA)
- Apply early and hear back early, but you are not bound to attend.
- Regular Decision
- The standard application timeline, with deadlines usually in December or January.
- Likely letter
- An early signal from a school (common for recruited athletes) that an official admit offer is coming.
- Common App
- One online application you can send to hundreds of colleges at once.
- Common Data Set (CDS)
- A standardized report each college publishes with its real admissions numbers. The source of truth for stats.
- Reach / Target / Safety
- A balanced college list: reaches are a stretch, targets are realistic matches, safeties are very likely yes.
- Yield rate
- The share of admitted students who actually enroll. Schools care about it a lot.
Extracurriculars
- Extracurricular
- Anything meaningful you do outside required classes: clubs, sports, a job, research, the arts, or your own projects.
- Spike
- One area where you have gone deep enough to be undeniable. Depth beats breadth, every time.
- The four tiers
- How colleges rank activities, from Tier 1 (rare, national) down to Tier 4 (common membership).
- Recruited athlete
- An athlete a college coach actively wants on their team. A nice boost, but it is not the focus here.
College
- Major
- Your main field of study in college, the subject most of your classes are in and the one your degree is named after.
- Minor
- A smaller, secondary focus, fewer classes than a major, for going deeper in a second interest.
- Double major
- Completing the full requirements for two majors at once.
- Net price
- What you actually pay after financial aid and scholarships, not the sticker price.
