Frontiers of Information Technology & Electronic Engineering

I submitted three times. The first submission was rejected after exactly two months, and the editor suggested submitting to another journal. I made significant revisions based on the reviewer's feedback. The second submission was rejected approximately 15 days later, with the editor suggesting that I make further modifications before attempting to submit to the same journal again. I made significant revisions for the second time and also wrote a response letter (initially, I didn't upload it, but the editor returned it and requested that I include the response letter. In other words, for this second rejection, a response letter was required). After my third submission, I received minor revisions after 45 days. I completed the revisions within a week, and the journal accepted it in less than a week. The speed of this journal is truly impressive.

1. It has been three and a half months and I still haven't received the revised version. If it's urgent, you can politely send an email to inquire about the status with the editor, but it also depends on the reviewing speed of the reviewers.

2. I didn't realize if I needed to select OA after being accepted. The decision to accept was made in March 2022, and it has been over three months since then. After official revisions and polishing, the paper was uploaded to the official website. The website shows that it hasn't been edited yet and still needs cross-validation. Currently, it has been half a month since the revisions were made, and I'm still waiting for publication. It doesn't seem like the publication will happen so quickly.
