Is it better to study by yourself or sign up for class when taking the tour guide card?

Personally, I think it is better to report to class. . The tour guide exam is divided into two parts: written test and oral test. The written test is unified throughout the country. The four books: Basic Knowledge of National Tour Guides, Basic Knowledge of Local Tour Guides, Tour Guide Business and Policy and Law are relatively easier than the oral test, because they are all knowledge points in the books, but they are wide in scope and rich in knowledge points, which is a bit difficult for people with poor self-control ability to learn. If you sign up for the class, the teachers have many years of teaching experience and will definitely know which ones are the key points. . Self-study is basically impossible if you take an oral exam. . . I taught myself before, and I memorized the tour guide words in my hand during the oral exam. It took a long time to recite one, and then I gave up. . It was not until I signed up for class last year that I realized that the leading word was not a backrest, but a skill. . Last year, twelve scenic spots were basically visited at least once, and the tour guide's words were also impressive. . The oral test of the tour guide exam is "the scenic spot in front of Wanshou Mountain in the Summer Palace". In eight or nine minutes, all the questions were answered. .
