UPCAT Biology — Taxonomy & ClassificationConcept Map
UPCAT candidates who build concept maps early in review tend to retain Taxonomy & Classification better through the long stretch to exam day. The Taxonomy & Classification concept map on this page shows the sub-topics University of the Philippines includes most often in UPCAT Biology, and how they branch off the central idea.
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 Biology subtest is marked as "Core" in the official pattern, and Taxonomy & Classification appears in position 2nd of 7 in the UPCAT Biology review rotation. Passing mark: UPG ≤ 2.2 typical. Recent UPCAT 2026 papers have drawn roughly 20 questions from this subject.
