What separates the best study help for high school students?
Six services made this page, and the scores run from 8.8 down to 6.5. The split comes down to what each one does when you are actually stuck.
Khan Academy scores 8.8 and is Free. Teachers graded its explanations highest for calculus and chemistry, and Khanmigo walks you through the steps instead of handing over the answer. Its weak spots: no textbook-specific solutions, and humanities and essay help is thin.
Quizlet sits at 8.2 for $7.99. Learn mode schedules review and adapts, practice tests generate themselves, and Magic Notes turns uploaded notes into cards and outlines. The catch is that user-made sets contain errors, and textbook solutions are thinner than Chegg's.
Wyzant scores 8.0, priced from about $35/hr. It was the only service that gave useful, specific essay feedback, and tutors explained our calculus and chemistry mistakes better than any written answer. You pay per hour, and quality depends on the tutor you choose.
Photomath lands at 7.7, Free with Plus at $9.99/mo. It solved 19 of our 20 math and chemistry-math questions correctly with steps, and explains alternative methods. It is math only, and word problems and proofs are hit and miss.
Grammarly scores 7.1 at $12. It caught grammar, clarity and tone issues in our essay answers that teachers also flagged, and Pro adds a citation generator and plagiarism check. Writing only, and AI rewrite features blur the line on academic integrity.
Brainly is 6.5 at $3.99. Answers to common homework questions already exist and the free tier is usable, but it earned the lowest teacher grade, with several confidently wrong answers.
What should you check before buying?
Our scoring puts answer quality at 30, coverage at 20, study tools at 20, value at 20 and learning & integrity at 10. Weigh your own subject mix against that.
- Subject fit: Photomath is math only. Grammarly is writing only. Khan Academy is thin on essays.
- Who answers: Wyzant uses one-to-one tutors. Brainly uses community answers, not experts.
- Cost shape: Free tiers exist on Khan Academy, Photomath and Brainly. Quizlet is $7.99, Grammarly $12, Wyzant from about $35/hr.
- Integrity: Khanmigo guides through steps rather than giving the answer; Grammarly's AI rewrite features blur the line.
