Questions
Are the answers right?
Every numeric answer is computed by code, not guessed, before you see it. Each problem shows the given values so you can check the setup.
Can I see the full solution?
Yes. Every problem has a step-by-step solution, and you can watch it worked out on the chalkboard or ask about any step.
Does it work for my class?
If your class has notes, slides or a syllabus, yes. Students use it for calculus, organic chemistry, physics, statics, biology, economics, statistics, psychology, history and more.
How much does it cost?
Your first crash course is free and needs no card. After that, Pro is $12.99 a month and you can cancel anytime. You can also pay $39 once for a semester (4 months, no auto-renew) or $99 for a year.
Practice it before it counts.
Your own private course, built from your syllabus, your notes and your professor's problems.
