How do I convey "As you all know"?


Having been trying to write a "sakubun", I must say that I had some trouble to
find a reliable translation for the phrase "as you all know" such as:

> **As you all know** , the education system in our country is not so good as
> it's claimed to be.
>
> **As known by all of you** , the education system in our country is not so
> good as it's claimed to be.

I'd appreciate if you translated the whole sentence; however, it's not really
necessary.

よろしくおねがいします！




What you're looking for should be `ご存じの通り` or `ご承知の通り`

> ご存じの通り、我が国の教育制度は、（+実際には）、言われているほど（or 言われるほど）良いものではありません。
