Dear native English speakers,
I have a little question.

Is the sentence above wrong?
In my knowledge, it is grammatically correct.

It's from an English grammar site : Pronouns Exercise

Thanks in advance.
Hirashin

The sentence is fine, but the expression is "to my knowledge", not "in my knowledge".

To my knowledge.
OK. I'll memorize it. Thanks, joadbres.
