Is the sentence below correct?
If you haven't finished your MR (morning reading), please finish it during the lunch break.
I want to send this message to our study group to remind people finishing their MR, which is their daily assignment.
As for me, the sentence seems all right. But after I checked the grammar of The Zero conditional, it seems the sentence is not acceptable.
If the above sentence is wrong, can I change it to 'For those who haven't finished the MR, please finish it during the lunch break'?
