Reasons why students lose points "unfairly" in Math
Sharing the reason why students often find it difficult to get full marks in the questions about recognition and understanding, teacher Le Anh Tuan said: “For students who have a clear goal of getting a high score in Math to compete for admission to top universities, they need to focus on thoroughly reviewing the questions at the application and high application levels.
However, an extremely important part that students often take for granted and think they can easily do correctly is the system of questions about recognition and understanding. This leads to a situation where students do not unfairly lose points on easy questions.
In the exam, the number of recognition and comprehension questions accounts for 60%, which is about the first 30 questions.
With questions at this level, candidates only need to have a firm grasp of textbook knowledge and quick thinking to be able to handle them. Regarding thinking, candidates need to practice 2 operations fluently: Regarding recognition, they must memorize and understand basic theory, regarding understanding, they must apply basic theory through calculation and thinking to solve the problem.
However, not everyone can do 30/30 questions at most. Because there are candidates who do it quickly and carelessly, leading to mistakes, or forget the basic formula system and theory, so they cannot handle it. There are candidates who rely too much on Casio calculators, leading to not having a firm grasp of basic knowledge and easily making mistakes when doing the test.
In general, for the recognition and understanding part, if candidates are really careful and pay proper attention, they will not make any unfortunate mistakes.
Notes on common comprehension questions that are often "tricky"
To help you avoid losing "unfair points" in the types of comprehension questions that are often "traps", Mr. Tuan said: To not lose many points in the recognition and comprehension questions, candidates do not need to be very good thinkers, they just need to have a firm grasp of basic knowledge and clearly classify the types of math.
When doing the test, you need to clearly separate the problem, and when it comes to basic knowledge, you must know all the theory of that part. Then you will definitely be able to answer most of the questions in this part. However, students often lose points in this part because the test sometimes "traps" very basic questions:
For example: With the problem of concluding the increasing and decreasing intervals of a function: Normally we often conclude that the function is increasing and decreasing only on the interval (a;b), but the exam concludes on the interval [a;b], so is that conclusion correct?
For the extrema section, clearly distinguish the terms extreme points of functions, extreme values of functions and extreme points of function graphs. If you cannot distinguish, you will make mistakes immediately.
With the domain of exponential functions, students often use casio calculators to do it. However, with exponential functions, most students will be wrong if they use casio calculators.
In almost any topic of analysis and geometry in grades 11 and 12, we can make mistakes when doing the exercises.
The comprehension questions are spread across all topics in grade 12 and some topics in grade 11. Almost every section will have knowledge from this section. Therefore, students should not only focus on reviewing a few specific topics, but must study all topics equally.
