St. Margaret’s Episcopal School uses the traditional Algebra I, Geometry, Algebra II and Precalculus sequence, not the Integrated Math I, II, III sequence used by the Irvine Unified School District, and grade levels in the two systems cannot be converted directly. Each level in the Mathematics Department has a standard and an honors section, and at the precalculus level the honors track branches two ways: Precalculus AB prepares students for AP Calculus AB, while Precalculus BC Honors and AP Precalculus prepare students for AP Calculus BC. This page organizes four paths by starting point and explains placement, the prerequisites at each step, summer courses, and the highest course a student can reach.
St. Margaret’s Episcopal School: Four Math Paths
Standard route (Geometry in grade 9)
- Grade 9: Geometry
- Grade 10: Algebra II
- Grade 11: Precalculus
- Grade 12: Calculus I, AP Statistics or Introduction to Data Science
Honors route (Geometry Honors in grade 9)
- Grade 9: Geometry Honors
- Grade 10: Algebra II Honors
- Grade 11: Precalculus BC Honors or AP Precalculus
- Grade 12: AP Calculus BC, or AP Calculus AB, AP Statistics
Accelerated route (Geometry finished in middle school; Algebra II Honors in grade 9)
- Grade 9: Algebra II Honors
- Grade 10: Precalculus BC Honors or AP Precalculus
- Grade 11: AP Calculus BC
- Grade 12: Multivariable Calculus or Linear Algebra, both Post-AP courses
Algebra I start (Algebra I in grade 9)
- Grade 9: Algebra I
- Grade 10: Geometry
- Grade 11: Algebra II, meeting the graduation requirement
- Grade 12: Precalculus; UC strongly recommends four years of mathematics
The paths differ by starting point, which is set by placement at entry. The standard path reaches Calculus I, AP Statistics or Introduction to Data Science in grade 12; the honors path reaches AP Calculus BC in grade 12; only the accelerated path, starting with Algebra II Honors in grade 9, completes AP Calculus BC in grade 11 and moves on to Multivariable Calculus or Linear Algebra in grade 12. Students starting with Algebra I complete Algebra II in grade 11, meeting the graduation requirement, and can take Precalculus in grade 12.
St. Margaret’s Episcopal School Math: Prerequisites at Each Step
The table below for St. Margaret’s Episcopal School is compiled course by course from the 2026-27 course pages. Courses marked as requiring Mathematics Department approval need department consent in addition to the prerequisite courses, and the course pages do not give specific letter-grade thresholds.
| Course | Prerequisite |
|---|---|
| Geometry | Completion of Algebra IB or Algebra I |
| Geometry Honors | Completion of Algebra IB or Algebra I and Mathematics Department approval |
| Algebra II | Completion of Geometry or Geometry Honors |
| Algebra II Honors | Completion of Geometry or Geometry Honors and Mathematics Department approval |
| Precalculus | Completion of Algebra II |
| Precalculus AB | Completion of Algebra II or Algebra II Honors and Mathematics Department approval; prepares students for AP Calculus AB the following year |
| Precalculus BC Honors and AP Precalculus | Completion of Algebra II Honors and Mathematics Department approval; prepare students for AP Calculus BC |
| Calculus I | Completion of Precalculus and Mathematics Department approval |
| AP Calculus AB | Completion of Precalculus or Precalculus Honors and Mathematics Department approval |
| AP Calculus BC | Completion of Precalculus BC Honors or AP Calculus AB and Mathematics Department approval |
| AP Statistics | Completion of Algebra II, Algebra II Honors, Precalculus or Precalculus AB and Mathematics Department approval |
| Introduction to Data Science | Completion of Precalculus; an elective for grades 11 and 12 |
| Multivariable Calculus (Post-AP) | Completion of AP Calculus BC and Mathematics Department approval |
| Linear Algebra (Post-AP) | Completion of AP Calculus BC |
Three patterns emerge. First, Algebra II Honors is the key step on the fast track: Precalculus BC Honors and AP Precalculus both require Algebra II Honors, and students in standard Algebra II can continue only to Precalculus AB or Precalculus. Second, AP Calculus BC has two entry points: directly after Precalculus BC Honors, or after AP Calculus AB. Third, both Post-AP courses require AP Calculus BC, so students who complete AP Calculus AB cannot enter them directly.
Mathematics courses require a grade of at least C- in the second semester to continue to the next level. The Mathematics Department overview updated in February 2026 lists the precalculus level as Precalculus, Precalculus Honors and AP Precalculus, while the 2026-27 course pages still list Precalculus AB and Precalculus BC Honors; follow the school's course request form for the current year.
St. Margaret’s Episcopal School Math: Summer Courses and Outside Courses
The Upper School summer session runs mathematics courses based on enrollment; the department overview lists Geometry and Algebra II Honors, both requiring Mathematics Department approval. The school does not publish summer session dates or fees online.
The School Profile states that only grades earned at the school appear on the transcript and in the cumulative GPA. The safest way to move a year ahead is therefore to confirm placement with the Mathematics Department before entry, rather than taking a course outside school first and then asking to skip ahead. For students in the school’s Middle School, the 2024-25 academic progression shows that grade 8 can reach Geometry or Geometry Honors.
The Highest Math Course Available at St. Margaret’s Episcopal School
At St. Margaret’s Episcopal School, mathematics continues beyond AP. The Mathematics Department overview lists two Post-AP courses: Multivariable Calculus, covering vectors, partial derivatives, gradients, Lagrange multipliers and multiple integration, with foundational ideas from differential equations and linear algebra; and Linear Algebra, which runs from vectors and systems of linear equations to eigenvalues, orthogonality and singular value decomposition. Both require AP Calculus BC. Following the prerequisites, a student who takes Algebra II Honors in grade 9 and Precalculus BC Honors or AP Precalculus in grade 10 can take AP Calculus BC in grade 11 and Multivariable Calculus or Linear Algebra in grade 12.
Beyond mathematics, there are two kinds of quantitative courses. One is AP Statistics and Introduction to Data Science: Introduction to Data Science teaches statistical inference through randomization and simulation, is open to grades 11 and 12, and requires Precalculus. The other is the Computer Science Department: after AP Computer Science A come Post-AP semester courses such as Artificial Intelligence Systems, Introduction to Software Engineering and Software Engineering, and Solving STEM Problems with Computer Science requires an AP science course and Precalculus BC Honors.

Math Pathways at St. Margaret's Episcopal School: Frequently Asked Questions
Irvine families often ask: how does St. Margaret's Episcopal School place students in math, and does it use the ISEE?
The school has not published its placement method. The Mathematics Department states that a math placement exam may be required to ensure proper placement of new students, but it does not publish exam dates, content or score requirements. Apart from standard courses such as Geometry and Algebra II, Geometry Honors, Algebra II Honors, Precalculus BC Honors, AP Precalculus and every AP and Post-AP course require Mathematics Department approval. Irvine applicants should confirm placement exam arrangements with the Admission Office and have middle school math transcripts and course descriptions ready.
After finishing grade 8 math at an Irvine middle school, what can a student take in grade 9 at St. Margaret's Episcopal School?
St. Margaret's Episcopal School uses the traditional Algebra I, Geometry, Algebra II sequence, so Irvine Unified middle school Integrated Math courses do not map directly and require placement by the school. Under the course page prerequisites, completing Algebra I (or Algebra IB) leads to Geometry or Geometry Honors, and Geometry Honors also requires Mathematics Department approval; completing Geometry or Geometry Honors leads to Algebra II or Algebra II Honors. UC also requires a year of geometry taken in grades 7 through 12, so students who skip geometry should keep this in mind.
Irvine families want to know: what is the highest math course at St. Margaret's Episcopal School?
St. Margaret's Episcopal School offers two Post-AP mathematics courses after AP Calculus BC: Multivariable Calculus and Linear Algebra. Both require AP Calculus BC, and Multivariable Calculus also requires Mathematics Department approval. Both are UC-approved honors courses and carry the same one-point weight as AP at the school. To take either course in grade 12, a student must complete AP Calculus BC in grade 11.
How do Precalculus AB, Precalculus BC Honors and AP Precalculus differ at St. Margaret's Episcopal School?
According to the 2026-27 course pages, Precalculus AB prepares students for AP Calculus AB the following year and requires Algebra II or Algebra II Honors; Precalculus BC Honors and AP Precalculus both prepare students for AP Calculus BC and require Algebra II Honors and Mathematics Department approval. The Mathematics Department overview updated in February 2026 lists this level as Precalculus, Precalculus Honors and AP Precalculus and no longer includes Precalculus AB. Irvine families should follow the school's course request form for the current year.
Can students take math ahead in the summer at St. Margaret's Episcopal School? What should Irvine families know?
Yes, but the options are limited. The Mathematics Department overview states that the Upper School summer session offers Geometry and Algebra II Honors based on enrollment, both requiring department approval. The school does not publish summer session dates or fees online. The School Profile states that only grades earned at the school appear on the transcript and in the cumulative GPA, so students who want to take courses ahead should first confirm with the Mathematics Department whether a summer course can be used to advance.
Irvine families ask: are St. Margaret's Episcopal School honors math courses weighted by UC?
Some are. On the UC 2026-27 A-G list, Precalculus BC Honors (listed by UC as Precalculus (H)), AP Precalculus, AP Calculus AB and BC, AP Statistics, Multivariable Calculus and Linear Algebra are all UC-approved honors courses. Geometry Honors and Algebra II Honors each add 0.5 grade points at the school but count as standard courses for UC.
