Alhamdulillah. I already submit a paper in a Journal (Q1 in Scopus). It is the seventh submission of the paper after six times rejection. I have learned much this time. Some of the lesson learnes are belows: a. Authorship Order and Changes i. Elsevier Journals (e.g., Energy and Sensors & Actuators Physica A) have a relatively flexible policy ii. AIP (e.g., Journal of Rheology and JAP) has a strict policy, but there is a leeway by requiring the approval from all authors if there is any change in the order and/or additional/removal of author/s name. iii. Springer (from my friend case, I forgot the journal name) has a stricter policy, not possible to add more authors while submitting the revised version. (Disclaimer: Only for the known journals, other journals in the publisher may have a more lenient policy) b. The review time i. Journal of magnetism and magnetic materials, and Sensors & Actuators Physica A : Medium, about 2
