Familiar, lack of breakthrough, few candidates achieved 9-10 points

Mr. Hong Tri Quang, a Math teacher at HOCMAIEducation System, commented that the 10th grade Math entrance exam in Hanoi this year still maintains a stable structure compared to recent years. In addition, the exam is still differentiated to ensure the requirements and nature of an entrance exam.

Regarding the scope of knowledge and difficulty, Mr. Quang said that the exam structure still includes 5 major problems, each problem consists of many small ideas arranged in order from easy to difficult. The familiar structure of the problem has not had a breakthrough in the past few years. On the other hand, this year's Hanoi 10th grade math exam has increased slightly in difficulty compared to 2022, with good differentiation.

"It is expected that the average score of candidates will be around 6 - 7 points, with a few 10 points," teacher Quang predicted.

Mr. Do Van Bao, a Math teacher at Vinschool, said that the exam meets the requirements for student assessment and has differentiation factors. The test content is high in basic knowledge and skills, not too challenging for students. Candidates only need to have time to review, practice solving basic math problems well and do the test carefully to be able to complete 75% to 80% of the exam quickly.

Moreover, some questions differentiate students but are not too difficult, students can still think to find a solution.

Mr. Bao also analyzed each question in detail. Lesson 1, which is part of basic knowledge about calculating the value and simplifying expressions with known results, is quite simple, creating conditions for students to be meticulous in order to get points easily.

Students only need to do the test carefully and present the first point fully. The second point requires simplifying the expression by knowing the result in advance, so it is difficult for students to make mistakes. The third point is also a familiar question, so many students will certainly get full marks in this test. However, students need to pay attention to the conditions to avoid being unfairly deducted points.

In part 2, in question 1, the type of problem is solving by setting up an equation or system of equations related to work productivity. Students can easily analyze the problem of setting up a system of equations or a system of equations and solving the equation/system of equations, achieving maximum score for this question. In the quality assessment questions and mock tests of some schools, question 1 is often given, students have good conditions to review.

Question 2 is about a simple practical problem related to knowledge of spheres. Students only need to remember the formula for calculating the volume of a sphere and carefully calculate to get points.

Lesson 3 - This is a fairly simple question that is easy to score. In point 1, students often solve it by using the auxiliary variable method. Students also need to pay attention to the presentation, consider the conditions of the variable, and conclude the final solution to achieve maximum points. Students from average to above can do well on this question.

Point 2 is related to knowledge about the intersection between a parabola and a familiar straight line. Average students and above can achieve point a of this question, good students can do well in point b. However, to achieve maximum points, it is necessary to pay attention to the factors of finding conditions, presenting carefully, and arguing tightly.

Lesson 4 - a pretty good geometry exercise, classifying students well at the end. The geometry exercise does not start with a familiar circle or semicircle, but in return there are many elements to suggest doing questions 1 and 2. Students read the requirements of the question carefully, carefully draw a picture that can do part 1 of the problem because this part is a basic knowledge part that is quite familiar in the review process and appears quite a lot in the survey exam as well as the mock exam of the schools.

Idea 2 requires more thinking from students, not as simple as idea 1, students must reason to prove that angles are equal based on parallel relationships and inscribed quadrilaterals.

Idea 3, the classification of students is quite clear, good students have to think a lot to be able to complete this idea. Students need to have good skills in proving similar triangles, inscribed quadrilaterals and good ability to see shapes.

Lesson 5 - The question about extreme values ​​is quite good but not too difficult. The expression is in symmetrical form so we can easily find the point of the problem. Students need to use appropriate transformations, combined with using the addition inequality and denominator, from there deduce what needs to be proven.

Overall, Mr. Bao predicts that this year's scores will probably have many 7s and 8s but few 10s. The density of scores between 6.5 and 8 accounts for the highest percentage.
