Should I Wait for a Journal's Decision Before Revising Authorship? I have submitted a paper to one of Elseveir Journal, My senior asked me to put him as a corresponding author but I put myself as a corresponding author assuming it is possible to change corresponding author. However, she asked me to request to journal editor immediately. I have sent a request as my senior suggested, I got response from editor like this...

"There is a 90% chance your paper will be rejected, i which case it doesn't matter, and a 10% chance you will be invited to submit a revision".

The journal impact factor 4.034 and their acceptance rate is 7%.

This is my first experience on submitting paper to any journal so I am afraid and wondering whether it is worth withdrawing paper and proceed for another journal.
You have been given the answer by the editor: That it doesn't matter yet.

Tell the other author of the paper that you asked, and the editor said to deal with it if/when you're asked to revise the paper.

Then move along with your life and work and wait for a reply. You absolutely shouldn't withdraw the paper for something like that when you've already been told how to handle it by the editor.
