Very informative kind of good tests of all time! I'm very interested in them and try to find time to do them all.


In test 1, why is it
Your limitless enthusiasm and energy were a valuable contribution?

rather than

Your limitless enthusiasm and energy were valuable contributions?

I thought the "valuable contributions" should be plural to agree with the subjects and verb.

Thank you!


Punctuation and capitalisation are definitively my weak points. As a non-native English speaker, I'm just glad I got grammar and words right!

Hi Frank,

Good point! I believe both "contribution" and "contributions" work in the sentence. I chose "contribution" to make the verb error a bit more challenging to catch. I believe "contribution" works because one might write "Your contribution of limitless enthusiasm and energy . . . "

Thanks for asking.


Lynn Gaertner-Johnston

Phorntita and Deborah, thanks for commenting. Deborah, I'm glad you had some success.

Hi Lynn,

As a non-native I have been able to correct the errors but I inserted some new errors. LoL..

For example, I unnecessarily corrected this sentence as:

"Since then he has been leading our process improvement efforts..."

Very interesting exercises indeed. Thank you.


Lynn Gaertner-Johnston

Hi Pankaj,

Thanks for trying the tests. Your version, "has been leading," is also correct--just a bit less concise.

Hello Lynn,

I found above proofreading exercises quite interesting. I tried to find out couple of mistakes but not all. It definitely gives me a proper direction how to proofread a document.

Thanks a lot.


Lynn Gaertner-Johnston

Sudhir, you are welcome. Thanks for stopping by.



Did you mean to misspell "Punctuation" in he "How did you do" section? It seems odd that you would miss that!


btw... correction on my end "the". I did not proof read my comment. :-)

Lynn Gaertner-Johnston

Hi Judy,

Thanks for the correction. Good catch! I will fix it now.
