Description
A large collection of Basic English idiom and Their equivalent in Persian.
The front side of cards filled with Persian Translation and the English idiom is on the back side.

I know the equivalent Persian, however not sure whether the English version makes any sense to a native English speaker.
Now, may I pick your brain?

Hello.

He knows what he's about.

I suspect that it's similar to, "He knows what he's doing." Context would help. However, there isn't any, is there?

**A large collection of basic English idioms and their equivalents in Persian.
**The front side of each card has a Persian saying. The back side has the English equivalent.

**I know the Persian saying, but I'm not sure if the English version makes any sense to a native English speaker.

As I said, "He knows what he's doing" is my best guess.

Yes, it's natural. It does mean "I know what I'm doing."
