Altering a thesis after acceptance?
When I submitted my MSc thesis, I thought my thesis was perfect (English/vocab/grammar). Now, every time I go back and read a section or chapter, I find some mistakes/things I will never use if I'm to write it now! I'm sure this will always be the case since your writing style/opinion will evolve and change. The point is to try to be better in your current work (thesis, papers etc). I wouldn't bother going back to FIX stuff but rather to see how much I have become better!
