UPCAT Physics — Electromagnetism, Mirrors & OpticsConcept Map
Concept mapping is a retrieval-practice technique that works especially well on wide chapters like Electromagnetism, Mirrors & Optics. When University of the Philippines writes a UPCAT Physics item that mixes two sub-topics, a concept-mapped reviewer sees the intersection in seconds. This page provides that map for Electromagnetism, Mirrors & Optics.
Exam context
The University of the Philippines College Admission Test is conducted by University of the Philippines and is scheduled for Mid-2026 (announced by UP Admissions). The Physics subtest is marked as "Core" in the official pattern, and Electromagnetism, Mirrors & Optics appears in position 6th of 6 in the UPCAT Physics review rotation. Passing mark: UPG ≤ 2.2 typical. Recent UPCAT 2026 papers have drawn roughly 20 questions from this subject.
