Basically, you can't return it. It's not about buying clothes. You don't have to return all the clothes you bought. Actually, I advise you to take the exam. This certificate is not difficult to test. If you are not confident, you can focus on one first, such as the futures market. Laws and regulations should be remembered, but this time it is the same. It passed in a flash and I worked hard for less than a month. This certificate is still very useful. China futures market needs talents like you, hehe.
