Assign it with a link.

How to assign it

• Stable links. Each lesson, notes page, unit sheet and free-response question has a permanent address, such as levlprep.com/precalculus/notes/<topic>.html. Links do not expire and need no account.
• Question sets. practice.html?topic=<topic> opens practice on one topic, practice.html?unit=unit-1 on a whole unit. Students get feedback and an explanation for every option. The practice page can also print a set as a worksheet.
• Free-response questions. Each has its own page with the prompt, the data and a printable answer sheet with lined space. Students write, then reveal the rubric and score themselves point by point. Nothing is graded by AI.
• Printing. Each lesson, notes page, unit sheet and free-response question has a Print button. A lesson prints all its parts in one run; a free-response question prints with lined answer space, and its rubric can print on a separate page.
• Google Classroom. The "Share to Google Classroom" button on each of those pages posts the link to your class.

No login for students

Students open a link and start. They need no account, and nothing they do leaves their device unless they choose to sign in. Progress, answers and scores are stored in their own browser, and typed free-response answers stay on the device they were written on.

Privacy, in short: no ads, no cookies, no tracking across other sites, and no new personal data collected from students. The site uses cookieless analytics and sends a short report when a page breaks. Details are on the privacy page.

Access for teachers and classes

Every notes page, the glossary and the unit sheets are free. Teachers can ask for free access to the rest of the course: email [email protected] from your school address. Ask about discounts for classes at the same address.

Alignment with the course framework

The units and topics follow the order of the course framework, mapped to our lessons. Unit 4 is not on the exam; it is here, marked "beyond the exam", because many classes teach it. Titles and explanations are in our own words; nothing reproduces the framework's text. It has not yet been reviewed by an AP® Precalculus teacher.

Skills

Each algebra topic sits right before the framework topic that first needs it.
