Read the source calculator notes

2025 source information. The introduction assumes candidates have access to a graphing calculator for A-Level and internal examinations and illustrates a TI-84 Plus CE Python. A question’s explicit no-calculator instruction still applies.

For a faulty calculator, the source names Learning Interactive Pte Ltd, The Resource Centre, Blk 231 Bain Street, #04-39 Bras Basah Complex, Singapore 180231; telephone 63334838; email learn@li.com.sg. It says warranty service requires an appointment by phone or email and the original “Record of Purchase” card. These are archived contact details, not a verified current service listing.

The source instructs students not to self-update from the TI website unless the version is approved by SEAB. This records the printed instruction; calculator approval and software requirements depend on the applicable examination notice.

The source photograph identifies the calculator model.
