Hi there
For us R&R students who are disappointed, confused, disheartened and the like, I found that the following link can give some generic instructions on how to act if one receives from minor to major corrections (including resubmission) - and some encouraging words to go with it.
Bottom of page: Dealing with corrections and revisions: http://www.reading.ac.uk/internal/studyadvice/postgraduates/sta-vivas.aspx#corrections
On an off, this advice would be useful to students from any university.
