IB Mathematics: The difference between AA and AI, HL and SL
The current IB Diploma mathematics is divided into two subjects:Mathematics: Analysis and Approaches (AA) and Mathematics: Applications and Interpretation (AI), each subject has two levels: HL and SL. The recommended teaching hours are 150 hours for SL and 240 hours for HL; the internal assessment Mathematical Exploration (IA, a mathematical exploration report of approximately 12 to 20 pages) in both subjects and levels will each count for 20% of the final grade.
Overview of the IB Mathematics Assessment Structure
| project | SL | HL |
| Recommended teaching hours | 150 hours | 240 hours |
| external assessment papers | Paper 1, Paper 2 (1 hour and 30 minutes each) | Paper 1, Paper 2 (2 hours each) + Paper 3 (1 hour, open-ended problem solving) |
| Paper 3 | Not available | HL proprietary, approximately 20% |
| Internal Assessment (IA) | Mathematical Exploration, 20% | Mathematical Exploration, 20% |
| calculator | Computers are not allowed for AA Paper 1; all AI papers are available at GDC | Computers are not allowed for AA Paper 1; all AI papers are available at GDC |
In terms of subject selection, AA focuses on the analysis skills of algebraic deduction, functions and calculus, and is suitable for studying engineering, mathematics, physics or quantitative economics in the future; AI focuses on statistics, modelling and the application of technology, and is suitable for design, social sciences and business analysis. IA topic selection is often the position that opens up the level - the topics are too big to complete, too detailed and not mathematically deep enough. We will provide step-by-step guidance on this part. See details IB Mathematics AA Tuition, IB Mathematics AI Tuition and IB/GCE course page.
IGCSE and Edexcel IAL Mathematics
IGCSE Mathematics is generally taken at the Form 3 to Form 4 stage, and is the branching point before IB or A-Level. Taking Pearson Edexcel International GCSE Mathematics A (4MA1) as an example, the course is divided into two levels: Foundation and Higher, using a 9 to 1 rating: Foundation can take grades 5 to 1, and Higher can take grades 9 to 4 (an additional grade 3 is set as the allowed grade). Each of the two papers is 2 hours long and each accounts for 50%. Cambridge IGCSE Mathematics (0580) is divided into two levels: Core and Extended. Extended covers deeper algebra and function content. Level selection will directly seal the upper limit of grades, so it is advisable to evaluate as early as possible.
Edexcel International A Level Mathematics is a unit system. The entire IAL consists of six units: Pure Mathematics P1 to P4 are compulsory core units, plus two application units, which can be chosen from Mechanics (M1, M2), Statistics (S1, S2) or Decision Mathematics (D1); IAS (AS level) is P1, P2 plus an application unit. The most common combination in practice is P1–P4 with M1 and S1. Note that the old C1 to C4 have been replaced by P1 to P4, please be clear when searching for old data.
