Summer courses with One Schoolhouse are intensive, for-credit opportunities for ambitious students. Students receive grades and comments in these classes, which are the equivalent of year-long, high-school courses.
This summer courses are offered in two distinct formats:
- Directed Studies | Students learn the same content with the same level of rigor but with greater flexibility: they complete the coursework over two consecutive four-week blocks, averaging 80-100 hours of work during each half. Students can work ahead at their own pace throughout the summer, structuring their learning around travel, jobs, camps, and other commitments. Unlike Traditional Courses, there are no weekly due dates in Directed Studies sections. This means students have significant autonomy in organizing their work. Students still receive regular instructor support, feedback on submitted work, and access to peers, but without the constraint of weekly deliverables. This format includes two major deadlines to ensure steady progress: students must complete at least half the course by July 10 and the entire course by August 7. The submission deadlines on these two dates are firm.
- Traditional 8-Week Paced | Our traditional format provides a structured eight-week experience with consistent weekly expectations. Students follow a schedule that quickly becomes routine with regular deadlines and predictable pacing each week. This format works well for students who thrive with external structure, prefer regular feedback and engagement with instructors and peers, and want a clear week-by-week roadmap through the material. Pacing for summer courses is fast; students should plan to devote 20-25 hours per week for all eight weeks to their course. Therefore, students must have availability to complete course work daily between June 15-August 7.
This dual-format approach allows students and families to select the learning structure that best matches their needs, learning style, and summer commitments. Both formats maintain the same high academic standards and cover similar curricula. The difference lies in structure, pacing, and assessment expectations.
Cost of the course is $1,990.

Students who enroll in an online course will have an online One Schoolhouse instructor, not an Ursuline instructor. A designated Ursuline administrator acts as the liaison with One Schoolhouse and shadows the progress of the students taking online courses. The Ursuline administrator periodically checks in with the students. The online course credit and grade will be reflected on the Ursuline transcript and included in the Ursuline GPA.
Students need to choose both the course and the desired format.

3611OLSG AP Precalculus Co-ed
(Junior-Senior) AP Precalculus centers on functions modeling dynamic phenomena and addresses the algebraic and trigonometric concepts that lay the foundation for either level of AP Calculus or its equivalent. This research-based exploration of functions is designed to better prepare students for college-level calculus and provide grounding for other mathematics and science courses. In this course, students study a broad spectrum of function types that are foundational for careers in mathematics, physics, biology, health science, business, social science, and data science. Throughout this course, students develop and hone symbolic manipulation skills, including solving equations and manipulating expressions, for the many function types throughout the course. Students also learn that functions and their compositions, inverses, and transformations are understood through graphical, numerical, analytical, and verbal representations, which reveal different attributes of the functions and are useful for solving problems in mathematical and applied contexts. In turn, the skills learned in this course are widely applicable to situations that involve quantitative reasoning. We recommend that students register for an AP Calculus course in the academic year following this summer course. This will allow them to further refine the skills necessary for achieving success on the AP® Pre-Calculus exam which is administered only in May.
