Unraveling IB Math Grading Criteria: Score Optimization Techniques for Math Geniuses
RevisionDojo.com offers smart tools and resources to help decode the IB Math mark scheme like an examiner. Understanding the marking scheme is essential for scoring well, as it rewards logical steps, proper notation, and reasoning.
The Marking Strategy
The IB Math mark schemes allocate marks primarily as Method Marks (M), Accuracy Marks (A), and Follow-Through Marks (FT), with additional considerations such as Misread Penalties (MR) that affect the final score.
Method Marks (M)
Awarded for correctly applying a method or starting the correct approach, these marks reward the logical steps and the correct setup of problems. It is essential to show your working because without earning method marks, you cannot earn the corresponding accuracy marks.
Accuracy Marks (A)
Given only after the method marks are earned, these marks reflect correct final answers or the proper application of calculations based on the method used.
Follow-Through Marks (FT)
These marks allow you to earn some credit if you make a mistake early on but then continue with logical and consistent work based on that mistake. FT marks appear mainly in multipart questions and encourage showing your reasoning even if earlier answers are incorrect.
Misread Penalty (MR)
If the question is misread (for example, misinterpreting key values or ignoring units), there can be a penalty, often resulting in loss of marks or limiting follow-through marks.
Maximizing Your Scores
This marking strategy means your final score depends not only on getting answers right but also significantly on demonstrating correct methods and logical work processes, even if a calculation error occurs. Showing clear, consistent reasoning and including units and rounding details helps maximize marks.
In summary, the hierarchy is:
- Earn Method Marks by correct process and setup.
- Earn Accuracy Marks by correct application and final answers, only if M marks are earned.
- Gain Follow-Through Marks for consistent work despite earlier errors.
- Avoid Misread Penalties by carefully reading and addressing the question properly.
This scheme helps encourage good problem-solving habits and rewards understanding over guessing.
For practical tips and examples on maximizing your marks following this scheme, resources like RevisionDojo provide self-marking worksheets and detailed walkthroughs.
In essence, to maximize your IB Math AA or AI results, focus on clear, logical, and complete working, showing your method step-by-step to secure M marks, which unlock the chance for A and FT marks.
- Always check the required decimal places or significant figures.
- The mathematical setup (equation or expression) is essential.
- Always label M, A, FT, or MR marks while marking.
- Every mark scheme is structured like a blueprint, with each mark (M or A) represented by a number.
- IB Math mark schemes often list multiple methods. Examiners are trained to accept correct, logical alternatives and award full marks for clear, justified reasoning, even if it's different from the model answer.

- If you skip working and just write the answer, you may get only a "G" (given) mark, not full credit.
- Even though calculators are allowed in Paper 2 (and both papers in AI), simply typing in numbers isn't enough. IB Math examiners want to see the steps and reasoning behind the calculations.
- When is MR Penalty applied? If the misread simplifies the question, making it easier to solve, a 1-mark deduction is typical. If the misread doesn't affect difficulty, and the rest of the method is sound, you may keep full marks. Rewriting your own wrong answer does not count as a misread.
- Always show the first correct step clearly to unlock M marks.
- Finance and statistics questions often require 2 decimal places or specific unit rounding (e.g., dollars, cm²).
- Follow-through can save your marks after an early error in multi-part questions.
- Highlight areas where you lost marks due to misread, no working, incorrect rounding, or ignoring calculator notation rules.
- Misread Penalty (MR) is applied if you misinterpret or copy the question incorrectly and deducts marks even if your math is correct based on that error.
- Misreads, often labeled MR in mark schemes, occur when you copy a number incorrectly from the question or interpret a variable or label inaccurately.
- Use two colored pens: one for marks awarded, one for errors when self-marking.
- Learning how to understand IB Math mark schemes is a powerful way to maximize your scores. The key is to treat them like a map, not a mystery.
- Common traps students fall into include not showing any method (no M mark, no full credit), writing correct answers and then overworking into an error, using incorrect or missing units in final answers, and rounding too early or inaccurately, especially in percentage or finance problems.
- Intermediate steps if the process involves multiple stages must be included.
- To maximize your IB Math scores, focus on earning Method Marks by demonstrating clear logical processes and correct method setup, as these are essential to secure Accuracy Marks. Learning the nuances of the IB Math mark schemes, such as Follow-Through Marks and Misread Penalties, can help you optimize your score.
