教えてください Anybody tell me

I'd like to know more about "Practical English Usage Diagnostic Tests: Grammar Tests to Accompany Practical English Usage" by Michael Swan.


Is it a revised version of "Grammar Scan: Diagnostic Tests for Practical English Usage" or each book is totally different?

If there is anyone who knows about it, please let me know.


少し気になっていることがあります。

Michael Swan著の「Practical English Usage Diagnostic Tests: Grammar Tests to Accompany Practical English Usage」は「Grammar Scan: Diagnostic Tests for Practical English Usage」の改訂版なのでしょうか？

あるいはそれぞれ全く別の内容なのでしょうか？どなたかご存知でしたら教えてください。
