1
Six sample plans for the start of the Physics or Engineering Physics major for students matriculating in AY 2025/2026 or later
(updated August 2025).
Matriculated before 2023/2024? See other tabs in this spreadsheet.
2
Each plan assumes a different starting point in math (MATH 19, 20, 21, or 51 or 61) and/or in physics (PHYSICS 41 or 41E, 43, or 61).
Take the Math and Physics Placement Diagnostics to receive advice on appropriate starting point, based on preparation.
