How to Pick High School Classes
How to pick high school classes that fit your goals, meet requirements, and leave room for sleep. A counselor's step by step plan for grades 9 through 12.
By Dana Whitfield, School Counselor
The direct answer: pick high school classes by locking in graduation and college prerequisites first, then choosing the most challenging courses you can sustain with solid grades, and leaving real room for sleep and activities. This guide walks the decision year by year, with the tradeoffs most students only notice after they have already missed a deadline.
Class Selection at a Glance
| Question | Answer |
|---|---|
| What comes first? | Graduation requirements and any college prep prerequisites for your goal schools. |
| Should I take the hardest class? | Only if you can earn a steady B or better. A failing grade hurts more than a standard class with an A. |
| How many APs? | As many as you can do well, often two to four by junior and senior year. |
| What about interests? | Electives show curiosity and can point to a major. They are not filler. |
| When do I plan? | Freshman year, with your counselor, then adjust every spring. |
Start With the Requirements
Every school district publishes graduation rules: a set number of English, math, science, social studies, and often world language credits. Colleges add their own expectations on top. Many selective schools want three to four years of a world language, for example, and four years of math through at least precalculus for engineering tracks. The College Board's BigFuture guide lays out a standard sequence most admissions officers recognize (College Board, BigFuture).
The mistake I see most is students filling electives first and discovering in junior year that they are one credit short of a requirement. Write the required courses per year before anything else. This frame stops the scramble.
List the non negotiables
Pull your school's course catalog and mark the classes you must take each year to graduate. If your school runs on credits rather than Carnegie units, convert to credits so the count is real, not a guess.
Check prerequisites now
Many courses need a prior class or a placement test. Algebra II usually gates precalculus, which gates calculus, and the chain starts in freshman year. Map it now so you are not blocked later. If you are unsure whether a class needs a test, ask the department chair before registration closes.
Balance Rigor and Grades
Colleges read both challenge and the grade next to it. The aim is the hardest schedule you can handle well, not the hardest schedule on the board. A student who takes four APs and earns three C's looks less prepared than a student who takes two APs and earns two A's.
Use a grade forecast
Look at your recent grades in the subject. If you earned a B+ in honors biology, AP Biology is a reasonable stretch. If you earned a C, standard biology protects your GPA and your confidence. The point is honesty about your track record, not ambition about who you wish you were.
A simple forecast keeps the choice concrete. Sketch the candidate course and the grade you realistically expect, then compare the two outcomes.
| Choice | If you earn an A | If you earn a B | If you earn a C |
|---|---|---|---|
| AP Biology (you had B+ in honors) | Strong signal | Still solid | Unlikely if prepared |
| Standard Biology (you had C in honors) | Safe and calm | Expected | Protects GPA |
The table is not a verdict. It is a way to stop guessing and start deciding from evidence you already have.
Avoid the all honors trap
A schedule of every advanced class can sink grades and sleep at the same time. Pick challenge where you are strong and keep standard where you are not. Admissions officers see the pattern. A transcript that shows smart placement reads better than one that shows exhaustion.
Match Classes to Interests
Electives are not padding. They show what you care about and can point to a college major or a career. A student who takes three years of computer science and leads the coding club tells a clearer story than a student with one of everything.
Try one exploratory class a year
A robotics elective, a journalism class, or a music theory course may reveal a path you had not considered. Sustained interest in one area matters more than a random spread across many.
Connect classes to activities
If you join the school paper, a yearbook or writing class supports it and gives you material for essays later. The same logic works in reverse. An activity you already love is a reason to choose the class that deepens it.
Plan the Four Year Arc
Course choice is a sequence, not one year at a time. Freshman classes affect senior options.
Front load requirements
Finish required base classes early so junior and senior years can hold AP, IB, or dual enrollment options. A student who delays world language to junior year often cannot reach the third or fourth year many schools prefer.
Leave room for life
Do not pack every block. A free period, a light semester, or a study hall protects sleep and the activities that make a transcript human. Our guide on protecting that time covers how to keep balance without losing rigor (how to balance school and extracurriculars).
A Sample Four Year Grid
Seeing a concrete grid helps more than abstract advice. Below is one pattern for a student aiming at a selective four year school, but shift it to your goals and your school's catalog.
| Year | Core load | Challenge add | One exploratory elective |
|---|---|---|---|
| 9 | English, Algebra I or II, bio, world history, language year 1 | Honors where offered | Intro CS or art |
| 10 | English, geometry or algebra II, chem, US history, language year 2 | One AP if ready | Journalism or music |
| 11 | English, precalc, physics, language year 3 | Two to three AP | Econ or psychology |
| 12 | English, calc or stats, senior science, language year 4 | Two to three AP or dual enrollment | Independent project |
This is a template, not a rule. A student who dislikes languages can sometimes substitute another credit, but check the policy before you skip year 4, since some schools weigh a third or fourth year heavily.
What if you change your mind
Most students do. The grid is a draft. If you discover a strength in sophomore year, swap an elective for a deeper class in that area junior year. The prerequisites you front loaded keep that door open.
AP, IB, and dual enrollment
Not every school offers all three. AP lets you take one course and sit one exam. The International Baccalaureate (IB) is a fuller program across subjects. Dual enrollment gives college credit through a local college. Use what your school offers, and do not panic if it offers only one path. Colleges read the pattern inside your school's context, not against a school across the country.
Talk to the Right People
Counselors and teachers know what fits your record and your school's quirks.
Meet your counselor early
They see the sequence, the prerequisites, and which teachers run a class at what pace. Bring a draft list so the meeting is a edit, not a blank slate.
Ask teachers about fit
A teacher can tell you if their honors class suits your record. They have seen hundreds of students attempt it and can place you honestly.
Common Misconceptions
- "APs always beat honors." Not if the AP grade drops. Colleges weigh the grade and the course together.
- "Electives are wasted blocks." Sustained electives build a story and skills that admissions readers remember.
- "I can fix prerequisites later." Chains like math and language rarely compress. Starting late usually caps your senior options.
- "My friend's schedule is my schedule." Goals differ. A pre med track and a film track need different ninth grade plans.
- "More is always better." Ten hard classes with no sleep produces worse outcomes than seven handled well.
Frequently Asked Questions
How many AP classes should I take?
As many as you can do well. Two to four in later years is common, but grades matter more than the count. One clean A beats two shaky C's.
Do colleges want all honors?
They want appropriate challenge with strong grades. A mix is fine and often smarter than a wall of advanced classes that lowers your GPA.
What if my school has few AP options?
Dual enrollment, honors, and rigorous electives also show challenge. Use what your school actually offers, and note the context in applications if needed.
Should I take a class I might fail to look impressive?
No. A low grade hurts more than a standard class with a strong grade. Pick the stretch that is one step past your record, not three.
How do electives affect college?
They show interests and can support a major story. Choose a few with intent, not random filler, and let them build across years.
When should I plan my four years?
Freshman year, with your counselor, then adjust each spring as grades and interests sharpen.
