UPCAT 2027 Comprehensive Study Guide and Test Reviewer

University of the Philippines College Admission Test (UPCAT) 2027 Reviewer Overview

The UPCAT 2027 Reviewer is an official document produced by the University of the Philippines (UP) Office of Admissions, located at the UP Campus, Diliman, Quezon City 1101. Copyrighted in 2026, this reviewer is designed specifically for bonafide UPCAT applicants to provide a realistic simulation of the examination environment and content. While it serves as a mini-version of the actual test, it contains only a fraction of the total items present in the full exam, and none of the specific questions provided in this reviewer will appear in the actual UPCAT 2027 session.

Terms, Conditions, and Ethical Guidelines

Applicants utilizing this reviewer must adhere to a strict set of terms and conditions. Failure to comply with these rules results in immediate disqualification from admission to the University of the Philippines. The conditions are as follows:

1. Confidentiality: The entire contents of the reviewer, including every test item, accompanying images, and provided solutions, are strictly confidential. No part of the material may be disclosed or made available for third-party use.
2. Non-Commercial Use: The reviewer may not be sold or utilized for any commercial purposes.
3. Individual Testing: Applicants must take the test independently; collaborative efforts or taking the test with another person is strictly prohibited.
4. Integrity: Any form of dishonest activity that impacts the individual's results or the results of others is banned.

Test Structure and Time Management

The UPCAT consists of four distinct subtests, each focused on a specific subject area and timed separately. Examinees are instructed to work as rapidly as possible without sacrificing accuracy. If a student finishes a section before the allotted time expires, they may review their answers for that specific part only; time cannot be carried over to other subtests.

1. Language Proficiency: Consists of $24$ items with a time allotment of $14$ minutes.
2. Science: Consists of $14$ items with a time allotment of $12$ minutes.
3. Mathematics: Consists of $14$ items with a time allotment of $16$ minutes.
4. Reading Comprehension: Consists of $24$ items with a time allotment of $18$ minutes.

Scoring System and Answer Sheet Protocols

The UPCAT utilizes a specific scoring formula designed to penalize blind guessing while rewarding educated guesses. For every incorrect answer, a deduction of one-fourth ($1/4$ or $0.25$ points) is made from the total score. Conversely, items left blank incur no deductions. Shading multiple options for a single item is automatically marked as a wrong answer and subjected to the same $1/4$ point deduction.

Proper shading is critical for the machine-reading process. A correct answer must be shaded heavily and completely within the oblong. Incorrect methods that will lead to answers being read as blank or wrong include:

• Using cross marks ($X$) or check marks ($\checkmark$) instead of shading.
• Crossing out an old answer instead of erasing it completely.
• Incomplete shading or shading too lightly.
• Shading beyond the borders of the oblong.
• Encircling the letter or putting unnecessary marks on the answer sheet.

Language Proficiency: English and Filipino Usage

The Language Proficiency section evaluates a student's grasp of formal standard usage, including grammar, spelling, punctuation, and vocabulary. A key passage provided in the reviewer discusses the psychological theories of Dr. Sigmund Freud regarding "unconscious" errors or parapraxes (commonly known as "Freudian slips"). Freud claimed these mistakes reveal hidden desires, fears, or hostilities. An example provided is a person using a house key on an office door, suggesting they would rather be at home.

Specific grammar and usage points highlighted in the practice items include:

• Distinguish between "hung" (for objects) and "hanged" (for execution).
• Correct usage of phrasal verbs, such as removing the unnecessary "for" in "requested for a scalpel."
• Contextual vocabulary (e.g., "furnish" meaning "to give" in a financial context; the idiom "against the grain" meaning something is irritating or contrary to one's nature).
• Logical sequencing of sentences to form coherent paragraphs.
• Tense consistency and reporting verbs (e.g., using "would" for future-in-the-past in reported speech).
• Filipino grammar: Identifying errors in sentence structure (e.g., the use of "Bagamat," "May paniniwala"), selecting appropriate vocabulary (e.g., "simbolo," "daan," "instrumento"), and utilizing correct prepositions (e.g., "ukol sa," "tungkol sa").

Science: Concepts and Logical Reasoning

The Science subtest covers Earth Science, Biology, Chemistry, and Physics. The questions require both factual knowledge and the ability to interpret data from graphs and diagrams.

Earth Science and Meteorology: Focuses on tidal forces (the combined effects of centrifugal force and gravitational pull from the Moon) and volcanic eruptions (driven by magma viscosity and dissolved gas concentrations). High viscosity and high gas content typically result in explosive eruptions.

Hydrology: A provided graph for the Meycauayan River shows the relationship between rainfall and water level increases. It illustrates the concept of lag time, which is the delay between the peak of rainfall and the peak of the water level increase. In the provided scenario, a $2$-hour lag time is identified.

Biology: Topics include plant transpiration (which is most rapid in hot, dry weather), evolutionary trees (cladograms) showing the relationship between species based on shared structures, and cellular biology. It notes that prokaryotic and eukaryotic cells both possess cell membranes, DNA, and ribosomes, but differ in organelles like mitochondria. Genetic engineering is discussed through the insertion of genes into bacterial plasmids to produce proteins like insulin.

Chemistry: Concepts include identifying homogenous solutions (e.g., aqueous solutions like $KOH(aq)$), stoichiometry, and molecular structures. For the reaction $2H_2 + O_2 \rightarrow 2H_2O$, reacting $2$ moles of $O_2$ with excess $H_2$ produces $4$ moles of $H_2O$. Molecular bonding identifies pi ($\pi$) bonds in double or triple bonds. Gas laws are applied to suggest that at $0^{\circ}\text{C}$ and $1\,\text{atm}$, equal moles ($10^{-1}\,\text{mole}$) of different gases ($H_2$, $He$, $O_2$) occupy the same volume ($V_{H_2} = V_{He} = V_{O_2}$).

Physics and Optics: Kinematics questions involve interpreting $y$ vs. $t$ (position-time) graphs for objects moving on an incline. Optics covers thin convex lenses: an object placed between the focal point and the lens creates a virtual, erect, and magnified image. Magnetism looks at configurations formed by bar magnets to determine the strength of the magnetic field at a center point.

Mathematics: Algebraic and Geometric Analysis

The Mathematics section involves complex computations across algebra, geometry, and logic. Key formulas and problems include:

Exponents and Numerical Evaluation: $\left( \frac{18 \times 10^4}{4 \times 10^{-3}} \right) + \left( \frac{4 \times 10^5}{-3} \right)^{-4}$

Work and Rate Problems: Archie eats a meal in $30$ minutes, Jughead in $10$ minutes. Together, their rate is $\frac{1}{30} + \frac{1}{10} = \frac{1+3}{30} = \frac{4}{30}$. The time taken is the reciprocal: $\frac{30}{4} = 7.5$ minutes.

Linear Functions: Costs of fishballs are modeled linearly. If $15$ pieces cost $25$ and $27$ pieces cost $40$, the slope $m = \frac{40 - 25}{27 - 15} = \frac{15}{12} = 1.25$. The cost for $19$ pieces can be calculated via the point-slope form.

Arithmetic Progression: For terms $(3-x)$, $(2x)$, and $(3x+1)$, the common difference $d$ is constant: $(2x) - (3-x) = (3x+1) - (2x)$. Solving for $x$ and applying the formula for the $n$-th term ($a_n = a_1 + (n-1)d$) allows finding the value of $k$ in the 6th term $(6x-k)$.

Geometry: Includes investigating circle theorems (angle at the circumference vs. center), parallel line properties, and areas of composite figures (e.g., areas of squares and triangles within grids).

Logic and Probability: Includes the calculation of conditional probability from a census table (e.g., the probability a male is a smoker) and solving syllogisms (e.g., "All clowns are funny. Some mascots aren’t funny.").

Reading Comprehension: Thematic and Narrative Analysis

Reading Comprehension tests the ability to analyze tone, theme, and purpose across several texts:

1. Metaphorical Life (The Bamboo): Uses the bamboo to represent the flexibility and endurance of life. It contrasts the roles of the older generation (dreams/stability) and the younger generation (visions/progress/innovation).
2. Political Poetics: A poem about the power of the ballot box and equality. It emphasizes that on election day, the "plain man's common sense" is equal to the "pedant's pride," and the vote represents a power that cannot be bought.
3. Historical/Social Issues (Comfort Women): Discusses the "Filipino comfort women" during the Japanese occupation. It explores themes of heroism, military despoilation, and the inherent humanity of victims relative to those who abuse power.
4. Data Literacy: A comparative graph shows student scores in Science subtopics when taught in English versus Filipino. This data serves as a basis for evaluating language policies in education.
5. Biodiversity (The Banog): A text on the Philippine Eagle (Haribon or Banog), the largest eagle in the world, found in Luzon, Samar, Leyte, and Mindanao. It identifies threats such as logging and kaingin and mentions conservation efforts like the Philippine Eagle Foundation (releasing eagles named "Pag-asa," "Pagkakaisa," and "Pangarap").
