First of all, you are an adult. Think twice before you do something, thinking that once you decide, it will not only cost you money, but also cost you time. There will be all kinds of things waiting for you, such as buying books, training classes, registration, written tests, oral tests and so on. So thinking clearly is the first task.

Secondly, why do you want to take a tour guide card? What is this for? If you just want to play, forget it, because it is not worth it. From the beginning of your preparation to the end, you are lucky to get a tour guide card. At least it costs 1500, and there are all kinds of indirect costs, which add up to a lot. I won't be a tour guide in the future. I have to pay for the annual review, and it will be invalid after the time.

Finally, as you said, you like to be a tour guide, but I think with your love, you will work hard, and of course you will be full of hope to get good grades in the exam.

Finally, I wish you good results in the exam. Everything depends on yourself or money. It's simple.
