Command terms tell you exactly what the examiner expects. Filter by Assessment Objective (AO).
Every formula printed in your official booklet, organised by topic. Know exactly which ones are given — and which ones you need to memorise.

Match your answer depth to the marks available.
Example questions:
You can still earn M marks even if your answer is wrong — always show your method clearly.
Example questions:
If you make an error in an earlier part, follow-through (FT) means you can still earn A marks in later parts using your wrong value.
Example questions:
R marks often appear in "justify", "hence", or "interpret" questions — always write a sentence explaining your reasoning.
Example questions:
No marks are awarded for AG questions if you work backwards from the answer. Start from first principles and show every step.
These concepts appear throughout Math AI SL exams. Master them to score higher.
Know how to perform regression, solve equations graphically, find intersections, and use statistical distributions on your calculator. GDC efficiency is the difference between finishing and running out of time.
The formula booklet is provided in both papers. Know which formulas are given and which are not — some key ones (like compound interest) are included, others you must memorise.
Math AI questions are always set in real-world contexts. When a question asks you to "interpret" or "comment", your answer must refer back to the context — pure maths answers lose marks.
Round to 3 significant figures (3 s.f.) unless told otherwise. Keep full precision in intermediate working and round only in the final answer. State units where required.
Topic 4 (Statistics and Probability) is consistently the largest component in Math AI exams. Master distributions, hypothesis tests, and regression — they appear in almost every paper.
Learn from others' mistakes. These cost students marks every exam session.
Not recording GDC outputs in working
Both papers allow GDC use. Always write down what you entered and what the GDC returned — answers without visible working can receive zero marks.
Not showing working in "Show that" questions
The answer is already given in the question. You must show every step of working — you cannot assume the result.
Ignoring context in interpretation questions
Answers like "the gradient is 2" earn zero marks if the question asks what it means. Link every interpretation back to the real-world context.
Rounding intermediate working
Keep full calculator precision until the final step. Rounding too early causes accuracy errors that cascade through multi-part questions.
Forgetting follow-through marks
If you get an earlier part wrong, subsequent parts can still earn "follow-through" marks if you use your wrong answer consistently. Write method clearly.
Confusing "hence" and "hence or otherwise"
"Hence" means you must use the previous result. "Hence or otherwise" allows other methods. Ignoring this costs marks in "hence" questions.
20% of final grade • 6–12 pages
A written investigation in which students explore a mathematical topic of personal interest. The Exploration must demonstrate mathematical communication, personal engagement, and correct use of mathematical language and notation.
