UPCAT Physics — Fluids, Waves & LightConcept Map
Concept maps turn Fluids, Waves & Light from a list of facts into a connected picture. For UPCAT Physics, this visual makes it easier to see how Fluids, Waves & Light relates to other chapters University of the Philippines tests in the same paper.
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 Fluids, Waves & Light appears in position 5th 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.
