This sentence is very different for different people, and can be roughly understood from two angles, which are divided into candidates who apply for civil service examinations and training institutions that provide civil service examinations.

First, the candidate

People who take the civil service exam have different learning foundations. Some candidates have a good foundation and can be admitted to civil servants through their own self-study. Therefore, the civil service examination and training institutions are useless to him. But there are also candidates with poor foundation. If you don't take part in the training, you won't be admitted to the civil service at all. Therefore, such candidates naturally have no advantage and are much worse than their opponents. Even taking part in the civil service examination training may not have any effect, and the chances of being admitted to the civil service are not great. Naturally, they are far behind their rivals. From the examinee's point of view, it is people with poor foundation who take the civil service exam, and the success rate is not high.

Second, the civil service examination and training institutions.

It can be seen from this sentence that many people who take the civil service examination will choose to go to training institutions to apply. Some people may pin their hopes on training institutions after reporting for work because of their poor foundation. In the end, the effect was average, and civil servants failed the exam. Some people studied in training institutions, and after good results, their grades improved a lot, and finally they were admitted to civil servants; From this perspective, it is still necessary to find a reliable institution to apply for civil service training. Such institutions have rich teaching experience, which can help candidates find and fill vacancies, and finally let candidates realize their dreams of becoming civil servants. On the contrary, if the candidate finds an unreliable institution, the effect will be very poor, and it is better not to participate in the training.

In short, this sentence tells us that there are two purposes. Candidates are not afraid of poor foundation. As long as you study hard and attend training courses, you are likely to be admitted to civil servants. However, they must choose a good institution. Only such institutions can provide more help to candidates. In addition, candidates with poor foundation should never rely solely on training institutions. If a public institution fails, it is easy to fail the exam, and civil servants need to be fully prepared.
