How to study for the SAT on your own: a free self-study plan

You can prepare for the SAT on your own, and the best materials are free. College Board gives you eight full-length adaptive practice tests in Bluebook and a Student Question Bank with thousands of official questions. Khan Academy adds free lessons built in partnership with College Board. What self-study needs is a plan. Find your weak skills, practice them most days, log every mistake, and take a full practice test about every two weeks.

The free tools you'll use

Bluebook practice tests. College Board's practice test page lists eight full-length SAT practice tests, numbered 4 through 11, all free in Bluebook. College Board says they use the same multistage adaptive model as the real test. After each one, Score Details in My Practice shows every question, your answer, the correct answer, and an explanation.

The Student Question Bank. College Board's question bank lets you filter official questions by section, domain, skill, and difficulty. Its study plan page suggests exporting a set of questions without answers, working through them, then exporting the same set with answers to check your work.

Tailored Practice. After you take a practice test, Tailored Practice in My Practice builds sets of questions from the Question Bank based on your results.

Khan Academy. Khan Academy's Official SAT Prep is still free, and Khan Academy says it built the course in partnership with College Board. It did change when the SAT went digital. Khan Academy retired its older Official SAT Practice at the end of 2023. Since January 2024, it hasn't offered full-length SAT practice tests or linked to College Board accounts to import scores. Its Digital SAT courses have lessons, videos, and practice questions organized by skill, and in August 2024 Khan Academy expanded the Reading and Writing course to 11 units named after College Board's domains. Use Khan Academy to learn a skill and Bluebook for full tests.

An error log. A spreadsheet or a notebook works. You'll use it every day.

Step 1: take a baseline test

Start with one full Bluebook practice test. Take it timed, in one sitting, with only the 10-minute break between sections. That gives you a starting score and a list of misses you can sort by skill. If you want a quicker read before committing two and a half hours, SAT Owl's free 24-question diagnostic takes about 30 minutes and gives you a predicted score and the skills costing you the most points.

Step 2: turn your misses into a skill list

Open Score Details and tag every miss, and every question you guessed on, with its skill. Then pick the two or three skills with the most misses.

When two skills are close, weigh them by how often they appear. College Board's test specifications put Algebra and Advanced Math at about 35% of the Math section each, or 13 to 15 questions per test. Problem-Solving and Data Analysis and Geometry and Trigonometry are about 15% each, or 5 to 7 questions. In Reading and Writing, the four domains are closer in size: Craft and Structure is about 28%, Information and Ideas and Standard English Conventions are about 26% each, and Expression of Ideas is about 20%. A gap in linear equations will cost you more points than a gap in circle geometry.

Step 3: practice one skill at a time

A daily session should take 30 to 45 minutes and focus on one skill.

1. If you don't know the rule or method, learn it first. Watch the Khan Academy lesson or read a short guide on that skill.
2. Filter the Question Bank to that skill, starting at the difficulty where you miss questions.
3. Do 15 to 20 questions untimed, then check them.
4. Rework every miss before reading the explanation.
5. When you're getting nearly all of them right, move up one difficulty level.

Stay on a skill until your accuracy on medium questions holds up across two sessions, then add the next skill on your list.

Step 4: keep an error log

For every miss, write the question, the skill, what went wrong, and why. Sort each one into a cause: content gap, misread, careless slip, or time. Each cause needs a different fix. A content gap needs practice on the skill. A misread needs a habit, such as restating the question before you look at the choices.

After one to two weeks, rework the questions in your log without looking at your notes. Anything you miss again goes back on your practice list. The guide to reviewing a practice test shows a sample log and how to use it.

Step 5: retest every two weeks

College Board's study plan page recommends spacing practice tests at least two weeks apart when your schedule allows, and taking one at least two weeks before test day. Its help center says a practice test score is "highly indicative" of your real score, especially when you take it within a couple of weeks of the SAT with the same time limits.

Don't spend your official tests too early. Once you've seen a test, retaking it won't give you an honest score. Save at least two unseen Bluebook tests for the last month.

A sample week

This week assumes a full practice test on Saturday. On weeks without a test, use Saturday to redo error log questions and take one timed module, and keep Sunday light.

That's about eight hours in a test week and five to six in other weeks.

An eight-week outline

• Week 1. Take your baseline test, review it, and build your skill list.
• Weeks 2 and 3. Work on your top skill in each section. Take practice test 2 at the end of week 3.
• Weeks 4 to 6. Move to the next skills on your list and add timed modules on Fridays. Take practice test 3 at the end of week 6, two weeks before test day.
• Week 7. Fix what test 3 showed, and redo every question in your error log.
• Week 8. Keep sessions short. Skip full tests in the last three days, complete exam setup in Bluebook, and sleep.

If your test is three weeks away, use the 3-week study plan instead.

Staying on track without a teacher

• Register first. A test date on the calendar turns a plan into a deadline.
• Book your sessions. Put them on a calendar at the same time each day, like a class.
• Track accuracy by skill. A total score moves slowly. Accuracy on one skill can move in a week, and seeing it change keeps you going.
• Tell someone. Share your target score and test date with a parent or friend who will ask how practice is going.

Mistakes self-studiers make

• Taking test after test without reviewing. The test measures your score. The review and the practice afterward raise it.
• Practicing what's comfortable. Reworking the skills you already know feels productive and earns few points.
• Reading explanations without reworking the question. Try it again first, then read.
• Skipping timed practice. Accuracy without a clock can fall apart under one. Add timed modules from week 4 on.
