AP Calculus AB, built from your own notes
Photograph your class notes or upload your slides and X+1 builds a short course with practice questions from the limits, derivatives and integrals your class is covering.
Start FreeWhy AP Calculus AB is hard
Limits, derivatives and integrals build on each other, so a gap early on shows up months later. Many problems take several steps, small algebra slips can ruin an otherwise correct answer, and free-response questions expect you to justify your reasoning, not just give a number.
From your notes to a short course
Upload a photo of your notebook, a PDF, slides or a document. X+1 pulls out the concepts and formulas and builds a structured course with explanations and questions from your own material.
Practice and review
Create practice sessions and practice exams from your material, and keep rules and formulas fresh with flashcards and spaced review.
Homework, graphs and a step-by-step tutor
Upload finished homework and get feedback on each answer. Ask the AI tutor to work a problem step by step, and use the formula scanner to type or upload an equation and see a step-by-step solution with an interactive graph.
Frequently asked questions
Can X+1 check my calculus homework?
Upload a photo of your finished homework and X+1 gives feedback on each answer. Use it to see which problems need another look, then ask the AI tutor to explain the ones you missed.
Does X+1 include official AP Calculus AB questions or material?
No. X+1 builds from the notes, slides and documents you upload and writes practice questions from them. It is not made by or affiliated with the College Board, and it does not come with official AP exam questions.
Can I study AP Calculus AB in Hebrew and English?
Yes. X+1 and its AI tutor work in English and Hebrew, with a right-to-left layout for Hebrew, so you can ask for explanations in the language you think in best.
Will X+1 raise my grade?
X+1 is a study tool: it helps you organize your notes, practice and review. Results depend on how you use it, so we do not promise any particular score or grade.
