Is the sentence you are doing good correct?

The sentence "You are doing good" is grammatically incorrect in standard English.

Here's why:

* "Good" is an adjective, not an adverb. Adjectives describe nouns, while adverbs modify verbs, adjectives, or other adverbs.

* "Well" is the adverb form. To describe how someone is doing, you need the adverb "well".

The correct sentence is: "You are doing well."
