Graphic display calculators (GDC)
The International Baccalaureate positively encourages the use of graphic calculators throughout its diploma courses. In the USA the TI-83 Plus and the TI-84 Plus family are allowed for use on the PSAT, the SAT Reasoning Test, SAT Subject Tests and Math Level 1 and 2 Tests, AP Chemistry exam, AP Physics exam, and AP Calculus exam.
(British A-Level specifications allow graphical calculators in all modules apart from C1 but the calculator must not have an in-built computer algebra system, CAS.)
Though there are many suitable models for mathematical study at this level, this site makes particular reference to the TI range, specifically the TI-84.
Many pages throughout this site make specific use of graphic calculators. To find them simple enter GDC in the SEARCH box.
