Understanding the Differences Between IB Math SL and HL: Which Should You Choose?

24 Sep 2024

Choosing the right IB Math course is a crucial decision that can impact your university applications and future career path. With four different IB Math subjects available, it’s important to understand the differences to make the best choice:

  • Math Analysis and Approaches (AA) Higher Level (HL)
  • Math Analysis and Approaches (AA) Standard Level (SL)
  • Math Applications and Interpretations (AI) Higher Level (HL)
  • Math Applications and Interpretations (AI) Standard Level (SL)

This guide will help you decide which IB Math subject aligns with your academic goals and prepares you for university.

Understanding the IB Math Subjects

Higher Level (HL) courses are more rigorous, with three exam papers:

  • Paper 1: Non-calculator paper
  • Paper 2: Calculator-allowed paper
  • Paper 3: Investigation paper

Standard Level (SL) students have a slightly lighter load, with only two papers, making SL less demanding than HL.

Analysis and Approaches vs. Applications and Interpretations

  • Analysis and Approaches (AA): Focuses on calculus and algebra, ideal for students who enjoy theoretical math and problem-solving.
  • Applications and Interpretations (AI): Emphasizes statistics and real-world applications, perfect for students interested in practical uses of math.

Choosing the Right IB Math Subject for University

For Non-Math Related Degrees:
If you’re not pursuing a math-heavy degree, Math Applications and Interpretations SL (AI SL) is a good fit. This course is tailored for students heading into fields like Law, Humanities, or Languages, where advanced math isn’t required.

For Economics and Related Fields:
Considering a degree in Economics? Math Applications and Interpretations HL (AI HL) might be enough, but some top universities prefer Math Analysis and Approaches HL (AA HL) for its comprehensive coverage of calculus and algebra, which are critical in Economics.

IB Math HL Isn’t Always More Difficult

Many students believe that Higher Level (HL) math is overwhelmingly challenging, but this isn’t necessarily true. In HL exam papers, some questions are identical to those found in Standard Level (SL) papers. These overlapping questions are designed to help HL students score points more easily. This structure means that HL isn’t just filled with harder questions; there are opportunities built in to help boost your score.

Which IB Math Course Gives You the Best Chance for a 7?

A common myth is that taking the “easiest” subject, like Math Applications and Interpretations SL (AI SL), guarantees a 7. However, data shows this isn’t true. From 2023 to 2024, only about 3-4% of students in AI SL achieved a 7, the lowest among all IB Math subjects.

Conversely, Math Analysis and Approaches HL (AA HL) boasts the highest success rate, with 14-20% of students scoring a 7. Despite being the most challenging, AA HL rewards those who tackle its rigor with a higher likelihood of achieving top marks.

Comparing MAA SL and MAI HL:

If you’re deciding between Math Analysis and Approaches SL (MAA SL) and Math Applications and Interpretations HL (MAI HL), consider MAA SL if you’re aiming for a 7 in Math. Based on statistics from the May 2023 to May 2024 IB exams, MAA SL has a higher percentage of students scoring 6s and 7s compared to MAI HL. This suggests that MAA SL could be a more strategic choice for students who want to maximize their chances of achieving top scores.

Key Takeaways:

  • AA vs. AI: Choose AA if you excel in calculus and algebra; opt for AI if you prefer applying math to real-world scenarios.
  • SL vs. HL: SL courses are less demanding and suitable for non-STEM paths, while HL provides deeper mathematical knowledge crucial for STEM fields.
  • Scoring a 7: For the highest chance of scoring a 7, consider AA HL or MAA SL, both of which have the best track records for top scores.
  • HL Isn’t Always Harder: Remember, HL papers include some questions identical to SL, offering a mix of challenges and accessible questions to help you score.

Choosing the right IB Math subject is about aligning your strengths, university plans, and career aspirations. Make an informed choice to set yourself up for academic success.
