The usage of verb after "once"

[cyrusevilming]

Please advise the appropriate form of verb that can be used after "once" in the following circumstances.

"We will inform you about the examination result once completed."

"We will inform you about the examination result once have completed."

"We will inform you about the examination result once complete."

"We will inform you about the examination result once it is completed."

"We will inform you about the examination result once it has been completed."

None of them work without "of" or "about" after "inform".

I think Mike means after "you" in the above sentences.
;-)

 

[MikeNewYork]

Yes, I do.

 

[Matthew Wai]

Can a result be 'completed'?

 

[bhaisahab]

No, Matthew, but the examination can be completed.

 

[Matthew Wai]

But is it possible for the result to come out as soon as the examination is completed?
The sentences sound like the speaker will know the result immediately after it is completed.

Not a teacher.

 

[bhaisahab]

Yes, it's possible.

 

[cyrusevilming]

Thanks. I have already amended all of the sentences.

So, would you please advise which sentence is correct?

 

[Rover_KE]

If you go back and number them, #4 and #5 are correct, though I prefer 'of' rather then 'about'.
