When speaking correctly should good or well be used?

example: I am well. or I am good.
I think it is well.

It is well

Thanks because my old English teacher said well but my new one said good.

It depends on how you're using the word -- as an adjective or as an adverb.

"I am good" (adjective) means that I do something well.

"I am well" (adverb) means that I feel fine.

You're welcome! It's great that you're paying attention to the different uses of "good" and "well." When referring to oneself, "I am good" is used when you are describing your ability to do something well or when stating that you are morally upright or virtuous. On the other hand, "I am well" is used when you are describing your physical or emotional state, indicating that you are in good health or feeling fine. So, both "I am good" and "I am well" can be correct, depending on what you want to express about yourself.
