Calc Classroom Tips is an independent educational website. It is not affiliated with, endorsed by, sponsored by or otherwise connected to Texas Instruments Incorporated, the College Board, ACT, Inc., or the International Baccalaureate Organization.

Exam rules are a summary, not an authority

Exam calculator policies are set by the exam boards and can change between the last revision of a page on this site and your test date. Every exam page links to the official source it was checked against, and carries a “last updated” date. Even so, the authoritative document is always the official one: verify the current rule with the exam board and with your teacher or exam coordinator before test day. Never rely on a third-party summary — including this one — as your only check.

Educational information only

The tutorials on this site explain how to operate a graphing calculator. They are general educational information, not instruction tailored to your course, syllabus or exam, and they are not a substitute for your teacher's guidance or for the official manufacturer documentation. Calculator behaviour can differ between operating system versions and models; where a step does not work on your unit, consult the manufacturer's documentation for your specific model.
