MATH 121 (6.0 units)
💡Expert's Take
Queen's awards MATH 121 (6.0 units) for IB Mathematics HL with a score of 5 or higher — in every faculty except Smith Engineering, which grants no credit. MATH 121 is a full-year calculus course that satisfies degree requirements for most science and arts programs. However, students pursuing a Mathematics or Statistics degree plan face a critical conflict: the Math department requires MATH 120 specifically, and accepting MATH 121 credit blocks you from taking it. Your degree plan determines whether this credit is a win or a trap (Queen's IB transfer credit tables).
Queen's transfer credit tables list this subject as "HL Mathematics" without distinguishing between the two current IB streams — Mathematics: Analysis and Approaches (AA) and Mathematics: Applications and Interpretation (AI). Both AA HL and AI HL appear to fall under the same "HL Mathematics" row and receive the same MATH 121 credit. If you want certainty about how your specific stream is treated, contact Queen's Undergraduate Admission directly.
Understanding the difference between MATH 120 and MATH 121 is essential. Both carry the same official title — "Differential and Integral Calculus" — and cover differentiation, integration, and multivariable calculus. The difference is in approach and audience. MATH 121 emphasizes applications to biology, physics, chemistry, economics, and social sciences, and is explicitly designed for students pursuing a major or joint honours plan in a subject other than Mathematics or Statistics. MATH 120 takes a more theoretical, proof-oriented approach and is the course required for Mathematics and Statistics degree plans. Both are real, rigorous, full-year calculus — they simply serve different academic paths.
The exclusion rule is what creates the trap: Queen's allows a maximum of 6.0 units from the group MATH 120, MATH 121, MATH 123, MATH 124, and MATH 126. Once you hold credit for MATH 121, you cannot also take MATH 120. For most students this is irrelevant, but for anyone whose degree plan specifies MATH 120, accepting the transfer credit permanently closes that door.
What to watch for:
- Smith Engineering — no credit at all. The Engineering IB transfer credit table explicitly lists "No Credit" for HL Mathematics. Engineering students must take their own calculus sequence (APSC 171/172) regardless of IB score. This credit cannot be used toward any Engineering degree requirement.
- Mathematics and Statistics majors — do not accept this credit. The Arts and Science IB transfer credit page states that students who wish to access a degree plan in Mathematics must take MATH 120. Since MATH 121 is an exclusion to MATH 120, accepting the transfer credit bars you from the theoretical calculus stream your major requires. You would need to decline the credit and enrol in MATH 120 instead.
- Physics majors — you're fine. Unlike Mathematics, the Physics department accepts either MATH 120 or MATH 121 for all prerequisites and degree requirements. Upper-year physics courses list their calculus prerequisite as "MATH 120 or MATH 121," so this transfer credit works exactly as intended.
- Health Sciences (BHSc) — usable as an option course. The Health Sciences IB page confirms that MATH 121 transfer credit can be used as an option course in the BHSc degree plan and can be used to access upper-year courses that require MATH 121 as a prerequisite.
- Smith Commerce — the credit counts, but does not replace COMM 161. Commerce students receive MATH 121 (6.0 units), which sits on the transcript as a non-Commerce course. COMM 161 (Mathematical Tools for Commerce) is a separate, Commerce-restricted course with its own exclusion list (ECON 255, ECON 256) — MATH 121 does not appear on that list, so both can coexist on your transcript. The transfer credit counts toward your total degree units but does not exempt you from COMM 161.
- Exclusion cap matters if you have other math-adjacent IB credit. The 6.0-unit cap applies across the entire MATH 120/121/123/124/126 group. If you also hold transfer credit from another source that falls within this exclusion group, the total cannot exceed 6.0 units.
The decision framework is straightforward: Check your degree plan's calculus requirement. If it lists "MATH 121" or accepts "MATH 120 or MATH 121" — which covers the vast majority of Arts and Science programs including Life Sciences, general science majors, economics, and most social sciences — accept the credit. It saves you a full year of calculus. If your plan specifically requires "MATH 120" (Mathematics and Statistics plans) or "APSC 171" (Engineering), the transfer credit cannot help you and should be declined. If you are in Commerce, accept it — the 6.0 units count toward your degree even though you still take COMM 161 separately.
Students who need to decline transfer credit should do so before the end of fall term of their first year. The transfer credit policies page outlines the process and deadlines. Once the deadline passes, the credit is locked to your transcript.
Official award line (IB Mathematics HL):
Minimum score: 5
Credit granted (Arts, Science, Computing, Health Sciences, Nursing, Smith Commerce): MATH 121 — 6.0 units
Credit granted (Smith Engineering): No Credit
Exclusions: No more than 6.0 units from MATH 120/6.0; MATH 121/6.0; MATH 123/3.0; MATH 124/3.0; MATH 126/6.0

What about Standard Level (SL)? IB Diploma holders are also awarded three units of general credit for transferable SL courses — for example, Mathematics AI SL = MATH 1XX (3). SL credit is not available to IB Certificate students. See the full IB transfer credit table for details.
