The math exam has a high level of differentiation.

GD&TĐ - The Mathematics exam in the 2026 High School Graduation Examination strongly differentiates students in each section; the number of high scores will increase, but achieving a perfect score will be difficult.

The 2026 high school graduation exam will be the second year that its content is based on the 2018 General Education Program.

The structure of this year's Math exam is similar to the 2025 high school graduation Math exam. This helps students feel confident and avoid surprises during the exam.

Analyzing this year's exam, the teachers specializing in university entrance exam preparation in Mathematics at the Toan.vn education system have offered their assessments and evaluations.

The difficulty level is higher in each section.

The Mathematics exam in the 2026 High School Graduation Examination is quite well-differentiated, requiring candidates not only to have a solid grasp of knowledge but also to be able to apply it, think logically, and solve practical problems.

Instead of concentrating the difficult questions at the end of the exam, this year's test features challenging questions in each section.

The four-option multiple-choice section ensures a difficulty level that meets the recognition-comprehension requirements, but still includes some "trick" elements, requiring students to read the questions carefully.

The true/false and short answer sections both contain questions at the comprehension, application, and higher-level application levels, so above-average students are perfectly capable of answering many questions in these two sections.

The most difficult questions "continue" to be the probability questions, in which the game's probability questions have a unique and quite interesting concept.

True/false questions and short-answer multiple-choice questions continue to play a role in assessing candidates' reading comprehension, logical thinking, and problem-solving skills.

Predicting a more favorable score range in 2025.

Based on the difficulty level of this year's exam, the teachers at Math.vn predict that students will find it easier to achieve average to above-average scores. The overall score distribution this year will likely be about 0.5 to 1 point higher than last year.

The average score ranges from 5 to 6 points. The majority of students will score around 5-7 points (compared to last year's 3.5-6 points).

What should students prepare for the 2027 High School Graduation Exam?

The Math exam in the 2026 High School Graduation Examination continues to show a trend of assessing competence rather than simply testing the ability to memorize knowledge.

For students born in 2009, preparing for the 2027 high school graduation exam, the focus should be on solidifying foundational knowledge, reviewing important concepts from grades 10 and 11 if necessary; developing mathematical thinking, focusing on understanding the essence of knowledge rather than memorizing sample problems; improving reading comprehension and data analysis skills, laying the foundation for solving real-world problems well, and practicing with challenging, high-difficulty question types such as probability, spatial geometry, or economic problems.

Below are the suggested answers for the Mathematics subject in the 2026 High School Graduation Exam, compiled by the Toan.vn team of teachers.
