Mathematics is one of the most crucial components of the DOST-SEI Undergraduate Scholarship Examination, testing not only what you know but also how you apply logic, reasoning, and accuracy in solving real problems. This practice test is designed to help you strengthen your mathematical foundation and prepare for the actual exam with confidence.
The DOST-SEI Mathematics Practice Test consists of 40 multiple-choice questions carefully selected from various high school topics. After answering each question, the correct answer and detailed explanation will be provided so you can understand how the solution was derived. Reviewing the explanations will help you identify your weak areas and improve your problem-solving approach.

Major Topics Covered in the Actual Exam
The math section of the DOST exam measures a wide range of skills, from computation to critical thinking. Here are the main areas you can expect:
Arithmetic and Number Theory
Covers fractions, decimals, percentages, ratios, proportions, factors, multiples, and divisibility rules. These problems test your speed and accuracy in basic operations and logical reasoning.
Algebra
Includes equations, inequalities, exponents, radicals, polynomials, and algebraic expressions. You’ll need to manipulate symbols, form equations from word problems, and solve for unknowns.
Geometry and Measurement
Focuses on lines, angles, triangles, circles, polygons, perimeter, area, and volume. You’ll encounter both straightforward geometry questions and reasoning-based problems that test spatial understanding.
Statistics and Probability
Involves data interpretation, mean, median, mode, range, and basic probability concepts. These test your ability to analyze information and make logical inferences.
Word Problems and Quantitative Reasoning
Applies mathematical concepts to real-life scenarios, testing your comprehension, reasoning, and ability to choose the most efficient solution.
Tips for Solving Math Questions in the DOST Exam
Stay calm and manage your time wisely. Each question deserves focus, but don’t get stuck on one item too long. Skip it and return later if needed.
Read every question carefully. Pay close attention to keywords like “least,” “except,” “approximately,” and “ratio to.” Small details can change what the question is asking.
Estimate before solving. Sometimes a quick estimation helps eliminate wrong options, especially when time is limited.
Use scratch paper effectively. Write neatly and organize your solutions step-by-step to avoid careless errors.
Review your answers if time permits. Double-check your arithmetic, signs, and units—many students lose points due to simple oversight.
Most importantly, avoid using a calculator. The DOST exam tests your mental computation and analytical reasoning, so practice solving problems manually. The more you do, the faster and more accurate you’ll become.
Final Reminder
The Mathematics section may seem challenging, but every problem follows a logical path. Focus on understanding concepts rather than memorizing formulas. If you know why a rule works, you’ll remember how to apply it under pressure.
