Comprehensive UPCAT 2027 Reviewer Study Notes

UPCAT 2027 Reviewer Overview and Guidelines

This reviewer is a property of the University of the Philippines under the Copyright 2026 UP Office of Admissions, located at UP Campus, Diliman, Quezon City 1101. It is designed to provide bonafide UPCAT applicants with a realistic experience of the University of the Philippines College Admission Test. The reviewer represents a mini-version of the actual test and contains only a fraction of the items that will appear in the UPCAT 2027. The document explicitly states that the specific items contained within the reviewer will not appear on the actual examination.

Applicants must adhere to strict Terms and Conditions including keeping all contents, images, and solutions confidential and prohibiting their use for third-party or commercial purposes. Collaborative test-taking or any dishonest activities are strictly prohibited and will result in disqualification from admission to the University of the Philippines.

Test Structure and Time Allotment

The UPCAT consists of four timed subtests. Each part is separately timed, and examinees are not permitted to use extra time from one subtest for another. If a subtest is finished early, the examinee may only review answers within that specific part.

1. Language Proficiency: 24 items, allotted 14 minutes.
2. Science: 14 items, allotted 12 minutes.
3. Mathematics: 14 items, allotted 16 minutes.
4. Reading Comprehension: 24 items, allotted 18 minutes.

Test-Taking Strategies and Scoring Mechanics

Examinees are advised to work rapidly without sacrificing accuracy. Because the test is timed, it is recommended to answer easier questions first and return to difficult items later. The scoring system utilizes a penalty for guessing: while there are no deductions for items left blank, one-fourth ($1/4$ or $0.25$) of written wrong answers will be deducted from the total score. Choosing multiple answers for a single item will result in that item being marked as wrong and included in the deduction fraction.

Technical Instructions for the Answer Sheet

The Answer Sheet requires specific personal details including the full printed name (Last, First, Middle), ID Number, Reviewer Booklet Number, Birth Date (MM/DD/YYYY), and Signature. It also identifies the High School Name and Address, as well as the test session (Saturday/Sunday and Morning/Afternoon).

Proper shading is critical for the automated reading of results. Correct shading must be heavy and complete within the oblong. Incorrect shading methods that lead to wrong or blank results include putting cross marks (X), check marks, crossing out old answers instead of erasing, incomplete shading, shading all options, encircling letters, shading beyond the oblong, or shading too lightly. Unnecessary marks on the Answer Sheet are strictly prohibited.

Language Proficiency Content and Concepts

The Language Proficiency section evaluates vocabulary, grammar, usage, and sentence structure in both English and Filipino. One featured concept is the "Freudian Slip" or parapraxes. Dr. Sigmund Freud defined these as significant mistakes with hidden meanings that reveal forbidden wishes, hostilities, and fears, proving that the unconscious mind can control the conscious mind. For instance, repeatedly using a house key for an office door might inadvertently display a desire to be home rather than at work.

Grammar and usage errors highlighted include idiomatic and formal usage. Examples include the distinction between "hung" and "hanged" (e.g., "criminals were hanged" being the formal standard for execution) and the removal of redundant prepositions (e.g., "requested a scalpel" rather than "requested for a scalpel"). Contextual vocabulary includes "furnish" (to give or provide) and the idiom "against the grain" (referring to something irritating or contrary to nature).

In the Filipino subsection, emphasis is placed on national identity and culture. Key terms include "katutubong pamana" (indigenous heritage), "pambansang identidad" (national identity), and "panawagan" (appeal/action). Vocabulary items include "masasawata" (to be stopped/prevented) and "matayog" (high/creative in the context of imagination). Syntactic construction focuses on logical sentence ordering, such as the history of the Philippine flag being first used by General Emilio Aguinaldo on May 28, 1898.

Science Concepts and Detailed Item Analysis

The Science subtest covers Earth Science, Biology, Chemistry, and Physics. Earth Science items explain that tides occur due to the centrifugal force of the Earth-Moon system and the gravitational force exerted by the Moon on the Earth's oceans. Volcanic eruptions are classified based on magma viscosity and dissolved gas levels; an explosive eruption is most likely caused by high viscosity and a high amount of dissolved gases.

Hydrological analysis, demonstrated through the Meycauayan River data, shows a lag time between peak rainfall and peak water level increases. In Botany, transpiration in plants occurs most rapidly under hot, dry weather conditions.

Biology topics include evolutionary trees and cell theory. Relatedness in species is determined by shared structures (clades). Prokaryotic and eukaryotic cells share a cell membrane, DNA, and ribosomes, but prokaryotes lack mitochondria for ATP production. Genetics is touched upon via protein production (e.g., insulin), where marketable levels are achieved by inserting the gene into a bacterial plasmid.

Chemistry items require knowledge of solutions and stoichiometry. A homogenous solution is represented by $KOH(aq)$ (aqueous potassium hydroxide). In a reaction where $2 H_2 + O_2 \rightarrow 2 H_2O$, reacting two moles of $O_2$ with excess hydrogen yields $4$ moles of water. The subtest also covers molecular bonding, specifically identifying pi ($\pi$) bonds. Gas laws are applied to conclude that at identical temperature ($0^{\circ}\text{C}$) and pressure ($1\text{ atm}$), equal moles ($10^{-1}\text{ mole}$) of different gases ($H_2$, $He$, $O_2$) occupy the same volume: $H_2 = He = O_2$.

Physics problems involve kinematics and optics. Graphical representations of a ball rolled up an incline and dropped involve plotting displacement ($y$) versus time ($t$). In optics, a thin convex lens produces a virtual, erect, and magnified image when an object is placed between the focal point and the lens. Magnetism principles state that specific physical configurations of bar magnet poles will maximize magnetic field strength at the center.

Mathematics and Quantitative Reasoning

The Mathematics section focuses on algebraic manipulation, geometry, and logical reasoning. Calculations involve scientific notation, such as:

$\frac{4 \times 10^{-3}}{8 \times 10^{-4}} + \frac{1}{5^{-4}}$

Work-rate problems are present, such as determining how long it takes Archie (30 mins) and Jughead (10 mins) to eat a meal together using the formula:

$\frac{1}{30} + \frac{1}{10} = \frac{1}{t}$

$\frac{4}{30} = \frac{1}{t}$

$t = \frac{30}{4} = 7.5\text{ minutes}$

Algebraic expressions must be simplified for specific constraints ($x \neq -1$ and $x \neq -1/2$). Linear functions are used to model manufacturing costs (e.g., Beloy's fish ball factory cost updates). Arithmetic progressions focus on solving for variables within sequences. Functional analysis includes finding roots; for $f(x) = x^4 + x^3 - 6x^2$, if one root is $x=1$, the nature of the remaining roots must be determined.

Geometry topics include circle theorems (angle $∠BAC$ having a relationship with $∠CBO$ where the measure of the latter is $90^{\circ} - x^{\circ}$), parallel lines, and area calculations for squares (ABCD). Data interpretation utilizes comparative graphs of restaurant profits (Restaurant X vs Y) and census probability (probability of an 18-year-old male smoker). Logical syllogisms test consistency (e.g., "All clowns are funny. Some mascots aren't funny.").

Reading Comprehension and Literary Analysis

The Reading Comprehension section includes diverse texts: metaphors, poetry, historical essays, and data-driven reports.

1. The Bamboo Metaphor: Life is compared to a bamboo—flexible, open-ended, and enduring. The text emphasizes the synergy between the older generation's dreams and the youth's visions to create progress in Philippine history. It characterizes the youth as the "water of progress" striking the "rock" of the older generation's thoughts.

2. The Power of the Ballot: A poem celebrating the equality of men during elections. The "ballot box" is described as a throne, where the rich, poor, weak, and strong stand as equals. The right to vote is presented as an unbuyable power: "The wide world has not wealth to buy / The power in my right hand!"

3. History of Comfort Women: This text discusses Filipino comfort women during the Japanese occupation. It argues that their bravery in coming forward gives society a second chance at heroism and forces a reckoning with the "beast" of power abuse. It frames the victim as more likely to retain humanity than the abuser.

4. Science Language Data: A comparative graph shows student scores in science subjects (Life Science, Physics, Chemistry, etc.) when tested in English versus Filipino. Generally, scores in Filipino are lower than English across most categories like Nature of Science and Physics, serving as data for educational language policy.

5. The Philippine Eagle (Banog): Known as haribon or manaol, this is the world's largest eagle, found in Luzon, Samar, Leyte, and Mindanao. It was identified by John Whitehead in 1896. Due to logging and kaingin (slash-and-burn farming), it is endangered. Republic Act No. 6147 was passed for its protection. Breeding efforts by the Philippine Eagle Foundation have produced chicks named "Pag-asa" (1992), "Pagkakaisa" (1992), and "Pangarap" (1999).

6. Personal Reflection: A narrative about growing up in a household with a pianist mother and a writer father. It explores the transition from being an "audio/oral" learner who disliked reading to a mature individual who understands the value of books, demonstrating how parental influence and personal growth shape educational interest.
