Using a graphing calculator (GDC) correctly can significantly boost your performance on IB Math AA and AI exams. This guide outlines the rules, setup steps, and smart calculator strategies aligned with RevisionDojo support and blog resources.
Why Graphing Calculators Matter in IB Math
Graphing calculators are not permitted in Paper 1, but are essential in Paper 2 (SL/HL) and Paper 3 (HL only). They help with complex calculations, plotting, regression, and solving equations numerically (revisiondojo.com) (revisiondojo.com, plusplustutors.com, revisiondojo.com, revisiondojo.com, revisiondojo.com, numworks.com, geta7.com). In AA, Paper 1 focuses on theoretical algebra and calculus skills without calculator use, while in AI, Paper 2 and 3 require extensive calculator use for modeling and data analysis (revisiondojo.com) (revisiondojo.com).
Approved Calculator Models
Only non‑CAS versions of certain models are allowed under IB rules. Permitted calculators include:
- TI‑84 Plus (CE and Python versions), TI‑Nspire CX (non-CAS)
- Casio FX‑9860GII, Casio FX‑CG50
- HP Prime (non-CAS version)
Models with CAS features or stored programs that could determine answers symbolically are forbidden (revisiondojo.com) (revisiondojo.com).
Setting Up Exam Mode Correctly
Before each exam, activate your device’s Exam Mode (also called “Press-to-Test” for TI or “IB Exam Mode” on Casio/HP). Steps usually include:
- Reset all memory, delete apps and variables
- Engage IB-specific exam mode immediately before entering the exam room
- Do not access calculator between entering mode and the start of the exam (revisiondojo.com) (numworks.com, plusplustutors.com).
Forecasting Graphing Calculator Use by Paper
- Paper 2 (SL & HL): use GDC for solving equations, graphing functions, computing definite integrals or derivatives, and statistical operations.
- Paper 3 (HL): calculator essential for modeling, regression analysis, calculus-based estimation, and equation solving as part of extended problems (revisiondojo.com) (revisiondojo.com).
Effective Features & Shortcuts to Master
- Function plotting: Use Y=, adjust window, use solver or intersection features
- Regression & statistics: Enter data into lists, run "LinReg" or other regression tools
- Equation solver: Use Solver function or built-in equation solver
- Mode settings: Toggle radians/degrees, continuous vs dotted graph lines, wrap input mode, set exact arithmetic when allowed
Mastering these can save time in exams and improve accuracy (revisiondojo.com) (revisiondojo.com, numworks.com).
Common Mistakes and How to Avoid Them
- Using CAS functions: Using symbolic algebra features when not allowed can lead to disqualification
- Not clearing memory/apps: Stored notes or programs are prohibited
- Incorrect setup of exam mode: Calculator must enter IB-approved exam mode immediately before start
- Wrong calculator model: CAS-enabled calculators, even those functional in regular practice, aren't allowed
Follow IB-approved setup to avoid penalties (revisiondojo.com) (revisiondojo.com).
Frequently Asked Questions
Q1. Can I use a CAS calculator in Paper 2 or 3?
No—only non-CAS models are allowed for IB Math exams (revisiondojo.com) (revisiondojo.com).
Q2. When do I enable exam mode on my calculator?
Activate exam mode immediately before entering the exam room and keep it enabled for the entire test duration (revisiondojo.com) (revisiondojo.com).
Q3. Which calculators does RevisionDojo recommend?
TI‑84 Plus CE, TI-Nspire CX (non-CAS), Casio FX‑CG50, FX‑9860GII, and HP Prime non‑CAS—all approved IB models.
Q4. How should I practice with my calculator?
Simulate exam conditions by practicing past Paper 2 or 3 under timed conditions and exam mode, focusing on plotting and solving with the device (revisiondojo.com) (revisiondojo.com, revisiondojo.com).
Q5. What settings are helpful to adjust before the exam?
Adjust angle mode, graph display type, input wrapping, and clear memory. Learn shortcuts to speed up data entry and access frequently used functions quickly (revisiondojo.com) (revisiondojo.com).
Q6. Why does IB prohibit stored apps or notes?
To prevent unauthorized access to formulae or notes, ensuring fairness and requiring recall and reasoning—preserving academic integrity.
