From College Board: AP Chemistry Course and Exam Description (Fall 2024).

How the course works

Learned, not just watched

It starts from what you know

A short check before the course finds the topics you already have, so you skip them and start where you're shaky.

It follows the official outline

Units and topics come from the College Board's AP Chemistry Course and Exam Description, in its order. Nothing is added and nothing is dropped.

Each idea is shown, then checked

Lessons are narrated, and the picture draws itself as each part is named. After each idea the lesson stops and asks you a question.

What you miss comes back

A wrong answer gets an explanation of why. Topics you keep missing become catch-up lessons, and a tutor beside every lesson answers questions about what's on screen.

Questions

Asked often

Is this the official AP Chemistry course?

No. Tessorio follows the official topic list in the College Board's AP Chemistry Course and Exam Description, but it is not made, endorsed or approved by the College Board.

Are the questions real AP exam questions?

No. The check-in questions are written for each lesson to test the idea you just learned. They are practice, not past exam questions.

Can a teacher use it with a class?

Yes. On the Teacher plan, one AP Chemistry course is built for the whole class, and the teacher view shows each student's check-in accuracy, topic by topic.

What if I only need one unit?

Ask for just that unit, or a few topics. The course is planned around what you need, and the short check skips what you already know.

What does it cost?

The free courses in the Tessorio Library need no account and cost nothing. Plans are Self-learning $19.99 a month, Family $29.99, Teacher $19.99 and Course Creator $79. Paying yearly costs ten times the monthly price, so two months are free. Each plan includes the whole Library and a set number of new lesson minutes a month; watching and rewatching never use them.
