Q: Required Reviews Completed changed three time

Hi Aicha,

The status 'Required Reviews Completed' means the reviewer's comment on your paper has been finalized and sent to the handling editor of the paper. As you know, the journal editors are quite busy as they have to deal with many papers. There are papers on hold for editorial decision before your paper. After the editor completes those, the editor will finalize your paper based on the reviewer's comment.

So please be calm and patient. Wait for this month. If the same status stays on the 1st week of July, you can also write a formal mail to the editor to know the paper's status.
