Because exams are based on book knowledge, don't blindly rely on betting questions. If you have enough time and energy, it is recommended to attend face-to-face training and read more books in combination with online classes. After all, learning the knowledge in your head is more reliable than any bet.

You can learn the definition of "betting", so that you can rely on betting to get extra points on the basis of review, rather than relying entirely on betting to take the exam.
