DLSUCET Mathematics — Ratio & ProportionConcept Map
A visual concept map is the fastest way to remember how Ratio & Proportion connects to the rest of DLSUCET Mathematics. This page shows the key concepts, sub-topics, and relationships you need to anchor in memory before sitting for the DLSUCET 2026.
Exam context
For the De La Salle University College Admission Test, De La Salle University tests Mathematics under a "Core section" label, with Ratio & Proportion in the 2nd slot across 9 chapters. DLSUCET candidates must clear the Competitive overall score cut on the 2026 paper, which draws about a meaningful share of Mathematics questions. Date to watch: September–October 2026 (expected).
