The TI-84 Plus Graphing Calculator is ideal for high school math and science. Its MathPrint™ technology engages students by enabling them to enter fractions and equations in proper notation to they see it on the display exactly as it’s printed in texts and on the board.

Can the TI-84 Plus be used in examinations?

The TI-84 Plus graphics calculator can be used in most UK exams*, including GCSE, AS/A Level, Standard Grade, Higher Grade, Advanced Higher Grade and IB (International Baccalaureate) in reset mode.

The Joint Council for Qualifications (JCQ) publishes annual guidelines entitled 'General, Vocational and Diploma Qualifications Instructions for conducting examinations'.

In 'Preparing for the examination', the chapter 'Using calculators' states that calculators must not:
- be designed or adapted to offer any of these facilities:

  • language translators
  • symbolic algebra manipulation
  • symbolic differentiation or integration
  • communication with other machines or the Internet

Calculators must not:
- be borrowed from another candidate during an examination for any reason; (an invigilator may give a candidate a replacement calculator).
- have retrievable information stored in them.

This includes:

  • databanks
  • dictionaries
  • mathematical formulas
  • text

*excluding non-calculator papers
