The answer in the dream is a symbol of opportunity and effort.

The dream of the answer shows that there is ideological pressure in your heart.

To dream of not knowing the answer indicates that you still need to work hard.

To dream of finding the answer, predict that you will find new opportunities.

Dreaming that the answer to the exam is wrong is a typical anti-dream, indicating that you care about the exam very much, and you care too much about it, that's why you have such a dream. I once had a dream before the exam. I failed in all subjects and the final exam results were quite good. Too worried, it is better to use the time to prepare for the exam.
