The ACET (Ateneo College Entrance Test) is the entrance exam for undergraduate admission to Ateneo de Manila University. This guide breaks down all four sections plus the essay, a review timeline built around Ateneo's own testing calendar, and the questions students ask most — plus a free, timed mock exam that matches the real format.

Four multiple-choice sections plus a timed essay, taken in one sitting. Here's what each one covers and where students most often lose points.
Problem-solving across your senior high school math sequence.
Tip: Work fast, not perfectly — an educated guess beats leaving an item blank, since there's no penalty for a wrong answer.
Vocabulary, grammar, and reading comprehension in English.
Tip: There's no separate Filipino section on the ACET — put your review time fully into English fluency here.
Broad awareness of science, current events, arts, and culture.
Tip: This section rewards broad reading habits more than last-minute cramming — daily news and general science reading pays off here.
Pattern recognition using shapes and sequences, independent of language.
Tip: This section is pure pattern drills — the more timed practice sets you've done, the faster you'll spot the rule.
A timed writing sample assessing organization, clarity, and reasoning.
Tip: Practice under a strict clock — a well-organized, on-time essay beats an unfinished ambitious one.
Ateneo's ACET registration and testing windows are fixed months ahead — plan backward from test day rather than starting review whenever motivation strikes.
Sit a full mock before reviewing anything, including a timed essay. It shows you which of the four sections — and your writing — need the most attention.
Split review time in proportion to your diagnostic gaps. General Knowledge benefits from daily habits (news, general science) more than intensive cram sessions.
Abstract Reasoning improves fastest with short, frequent, timed practice sets rather than long infrequent sessions — layer in 15–20 minutes a day.
Write full practice essays under real time pressure, not just outlines. Confirm your testing center (Metro Manila or provincial) and what to bring on test day.
The Ateneo College Entrance Test (ACET) is the entrance exam required for admission to Ateneo de Manila University's undergraduate programs, administered by the university's Office of Admission and Aid.
For SY 2027–28 intake, Ateneo has scheduled the ACET for Metro Manila testing centers on September 19–20, 2026, with provincial testing centers the following weekend, September 26–27, 2026. Confirm current dates on Ateneo's official admissions calendar, since they shift each cycle.
The ACET is open to graduating Grade 12 students (and qualified transferees) applying to Ateneo de Manila University's undergraduate programs. Some applicants may instead qualify for Ateneo's separate International Baccalaureate (IB) & SAT admission route. Registration is done online through the Office of Admission and Aid during the announced application period — confirm current eligibility rules and deadlines on Ateneo's official admissions site before applying.
Multiple-choice questions in Mathematics, English, General Knowledge, and Abstract Reasoning, plus a timed essay segment that tests writing and reasoning skills.
No. Unlike the UPCAT, the ACET is administered entirely in English.
No. There's no right-minus-wrong deduction, so making an educated guess on a question you're unsure of never costs you points.
Admission is holistic: Ateneo weighs your ACET results alongside your high school academic record, extracurricular activities, personal essay, and recommendation letters — not the test score alone.
At Ateneo's Loyola Heights campus in Quezon City, or at one of the provincial testing centers set up across the country each cycle. The current list is published on Ateneo's official ACET testing centers page.
Take a full diagnostic mock — including a timed essay — before you review anything, then split your prep time across Math, English, General Knowledge, and daily short Abstract Reasoning drills based on where the diagnostic showed the biggest gaps.
