Is Khan Academy enough for SAT prep?

Khan Academy offers free SAT prep made in partnership with College Board, the organization that makes the test. It covers both Reading and Writing and Math, and for many families it's the first resource they turn to. Whether it's enough on its own depends on where your child is starting and what score they're aiming for.

What Khan Academy does well

Khan Academy is free. Families shouldn't have to pay hundreds or thousands of dollars for effective SAT prep.

The video lessons are well-structured and cover the foundational skills tested on the SAT. If your child needs to review algebraic concepts, brush up on grammar rules, or work through the fundamentals of reading comprehension, Khan Academy is a strong place to start. Because of the College Board partnership, the content is aligned with the skills and question types that appear on the test.

Where it falls short

It doesn't have its own practice questions or track progress. Khan Academy links to the College Board question bank rather than hosting practice questions on its own platform. Students click through to College Board to practice, then come back to Khan for lessons. There's no integrated experience where practice and instruction happen together, no mistake tracking, and no way to review past errors or see patterns in what's going wrong.

It doesn't teach Desmos. The digital SAT has a Desmos graphing calculator built into every Math section, and knowing when and how to use it effectively can significantly improve a student's Math score. Khan Academy's SAT prep doesn't cover Desmos at all, which is a meaningful gap for the current test. We've written about how to use Desmos on the SAT here.

It's designed for broad review, not targeted improvement. Khan Academy's lessons cover the basics well, but the platform doesn't identify specific weaknesses or give students a way to focus on them. A student who needs concentrated work on three question types gets the same general coverage as a student who needs to review everything. For depth on specific skills, resources like Erica Meltzer's reading and grammar guides go further.

It doesn't teach test-taking strategy. The SAT rewards more than content knowledge. Pacing, knowing when to skip a question and come back to it, reading answer choices strategically, and managing time during the test are all skills that affect scores. Khan Academy doesn't cover any of them.

The answer explanations focus on the right answer, not the misconception. When a student gets a College Board question wrong, the explanation walks through why the correct answer is correct. What it doesn't do is address why the student chose the wrong answer, what misconception led them there, or how to approach similar questions differently next time.

When Khan Academy is enough

For some students, Khan Academy is all they need. This tends to be true when the student is starting below 1100 and needs to build foundational skills in math, grammar, or reading comprehension. It also works well for students who are disciplined enough to follow a consistent schedule, review their mistakes on their own, and supplement with Bluebook practice tests independently.

When you need more

Khan Academy's limitations become apparent when a student needs more than video lessons and linked practice questions: when they need a study plan, mistake tracking, targeted drills on specific weak areas, or harder questions beyond what's in the College Board bank.

Sharp addresses these gaps directly. It has its own bank of expert-written questions at every difficulty level, tracks mistakes, identifies the specific question types costing your child the most points, and builds a personalized study plan around those areas. Its AI tutor explains wrong answers by addressing the misconception behind the error and teaching the student how to approach similar questions in the future, not just explaining why the right answer was right.

The best approach for most students

The strongest prep plan uses Khan Academy and other resources together rather than choosing one exclusively. Start with Khan Academy to build foundations and get familiar with the test. Take a Bluebook practice test to establish a baseline and identify weak areas. Then shift to more targeted tools for the specific work that will improve your child's score.

Khan Academy is a good resource. Whether it's enough depends on the score your child is starting from and the score they're trying to reach.

Sharp is built to enable every student to realize their academic potential, regardless of their starting point.
