You get one calculator and it must be non programmable. Proctors can inspect and reset it before the test. Bring a safe model and a fresh battery. That is the whole game.
Quick answer
-
One unit only inside the room
-
Non programmable scientific calculator
-
No borrowing or swapping once the test starts
-
Expect inspection and memory reset at the door
What PRC means by non programmable
A non programmable scientific calculator can perform standard scientific functions but cannot store formulas or run programs. It has no alphanumeric program editor and no computer algebra system. It may have multi line display, fractions, conversions, statistics, complex numbers, and tables as long as it cannot save user programs.
Features that are safe
-
Basic scientific keys sin cos tan log ln sqrt factorial permutations combinations
-
Fractions mixed numbers scientific notation engineering notation
-
Two line or multi line display
-
Complex numbers polar rectangular conversion
-
Basic statistics single variable and two variable
-
Unit conversions when built in
-
Table or function calculation that does not save user code
Features that get a unit rejected
-
Programming mode or program editor
-
User definable formulas stored in memory
-
Computer algebra or symbolic solve and integrate
-
Solvers that accept arbitrary equations and save them
-
Communication ports or wireless capability
-
Removable memory

Tip
If you see the word program or PRGM or PGM anywhere in the manual or menu choose another model.
How to check your calculator at home
-
Power on and scan the keys for a key labeled PRGM PGM Program or similar
-
Open the mode or setup menu and look for Program or Equation memories
-
Attempt to store text in any memory location. If you can type letters beyond variables for complex numbers the unit is likely programmable
-
Reset the calculator to factory state. Confirm that no custom formulas or code remain
-
Test a few standard keys sin cos tan log ln and a fraction to be sure the device works after reset
Exam day checklist
-
Bring one non programmable scientific calculator
-
Bring a spare battery in your bag if allowed by your site
-
Clean the device and remove crib notes or stickers
-
Know the reset sequence for your model
-
Arrive early so inspection does not cut into your time
-
If a proctor questions the model ask to perform a reset and show there is no program menu
Suggested buys by need
Budget student
Casio fx 82EX or Casio fx 350EX or Sharp EL 531. Light simple tough.
Statistics heavy exams
TI 36X Pro or Sharp EL 520. Good data and conversion menus without programming.
Transparent body option
Canon F 789SGA. Clear case makes inspections fast.

Notes
Display behavior and complex features vary slightly by sub model. All listed units are non programmable across retail versions.
What if your board issues a stricter list
Follow your Professional Regulatory Board program for the sitting you will take. If it names models or bans any specific series follow that instruction even if other sources say the unit is fine. When in doubt bring a second safe model to the venue and leave it with your bag.
Troubleshooting at the gate
Proctor says your unit looks programmable
Request a full reset and show the mode menu to confirm there is no program function.
Battery low
Ask permission to swap the cell before seating. If not allowed you must proceed as is. This is why a fresh battery matters.
Unit not on the posted list
Offer to show that there is no program menu. If the room policy still rejects it you must use a spare. Keep a cheap backup in your bag on practice days so the keys feel familiar.
Frequently asked questions
Can I bring two calculators
No. Only one inside the room. If you carry a spare leave it with your bag.
Is memory recall allowed
Yes for normal calculation memory like Mplus but you may be asked to reset before the test.
Are graphing calculators allowed
No. Graphing models are programmable or have advanced memory. They do not pass inspection.
Are fraction and equation solvers allowed
Fraction input is fine. Equation solvers that do not store user code are usually fine. If the solver saves formulas the unit will be rejected.
Are phone calculator apps allowed
No.
