A groundbreaking transformation of “Jin-Suk Son’s 900 English Grammar Problems”!
500 English grammar questions compressed to fit the new civil service exam!

Grammar study needs to change now.
Grammar is not English, it is rules.

“900 English Grammar Problems by Jin-Suk Son,” which has been loved by many students, has been republished as “500 English Grammar Problems by Jin-Suk Son” for 2025, with a reduced number of questions and in line with the changing trends in exam questions.

One of the most frustrating things I've seen while watching so many students preparing for the civil service English exam is that they miss the important parts and end up studying extensive grammar theory books, only to be unable to solve the problems in the actual exam.
Many test takers are so focused on interpreting grammar questions that they fail to grasp the examiner's intentions and end up misunderstanding the question.
In fact, with very few exceptions, in most cases, what is asked in grammar questions, that is, the intention of the examiner, is set.
It is important to be aware of these important points in advance.
Then, you need to practice applying those points when faced with real-world problems.


Looking at the new testing trends that will be implemented starting next year, we can see three changes.

First, the number of questions has been reduced,
Second, the writing problem disappeared,
Third, only underlined questions are given.


This is a welcome change for test takers who found grammar difficult.
First of all, the writing questions that test takers found burdensome have disappeared, and only underlined questions that clearly show the main points of the test are given, so there is no need to go through the trouble of finding the intention of the test yourself.
Although there are these changes on the surface, if you look at the content of the question, there is no significant difference from the previous questions.
Grammar points that were important in previous exams are still applied to new types of questions.


In line with this trend, there are several changes in 『Son Jin-sook English Grammar 500 Questions』 compared to the existing 900 questions.


1.
The biggest change is the reduction in the number of questions.
As the weight of grammar has decreased in the actual exam, it is no longer an area that requires as much time investment as before.
By repeatedly studying frequently asked grammar points in 500 questions, you can develop the ability to immediately find the correct answer on the actual exam.


2.
The writing problem has been deleted.
By removing frequently appearing auxiliary verb idioms and comparative idioms from existing writing tests, you can prevent wasted time studying content that will not even appear on the test.


3.
By underlining every question, you can practice reading the underline and immediately grasping the question's intent, which can help you dramatically reduce the time it takes to solve problems on the actual exam.
