이 책의 특징은 이렇습니다. 

하나, 공무원 시험에서 문법은 출제 경향이 뚜렷합니다. 나오는 부분이 정해져 있고, 그 부분에서 응용을 해도 합니다. 그러니, 출제되지 않는 부분을 건드리지 맙시다. 공무원 국어 문법은 단답식이라 암기가 되어야 합니다. 출제 범위를 똑 부러지게 정해놓고 그 부분을 이해하고 반복해야 합니다. 이 책은 문법 반복에 최적화된 문제집입니다. 더 이상, 학생들이 스터디 용도로 쪽지문제를 만들 필요가 없습니다. 999제 문법으로 준비합시다.

둘, 효율적인 책입니다. 품사는 299제, 띄어쓰기는 257제, 문장종류는 90제, 합성어와 파생어는 93제, 형태소는 50제, 음운종류 50제, 음운현상은 40제, 중의적 문장 30제, 높임법도 30제, 문장성분과 자릿수 40제, 부정문과 시제도 각 10제씩 만들어 넣었습니다. 한눈에 이론 정리가 되면서, 빠른 정리가 가능하도록 문제를 만들었습니다. 문법 정리 시간을 절약하는 데 가장 빠릅니다.

셋, 공무원 국어에서 문법의 출제 유형인 것에서는 빠짐없이 모두 연습문제로 만들었습니다. 모두 새로 만든 문제이고, 해설도 꼼꼼합니다. 기출은 이미 답을 외우고 있어서 새로운 문법문제가 필요할 때, 이 999제를 활용해, 실력을 탄탄히 하도록 했습니다.

문법은 처음에는 어렵지만, 이론 듣고 바로 문제로 풀면서 정리하면 빨리 정복할 수 있습니다. 이 책으로 원하는 합격을 올해, 이루기를 바랍니다.
