A friend has asked me to proofread their cover letter and CV for applying to a PhD position. I've done such proofreading when it was about more-or-less unskilled labour, or for friends who'd done a Bachelor's or Master's degree and were applying somewhere at some company. Never for a PhD, and I'm generally wondering what differences there are.
Specifically, the cover letter has the "thank you for your consideration" phrase at the end, followed by an "appreciate the opportunity to meet" phrase. A PhD is not a very common thing, so my question is: how appropriate (or not) is it to use such omnipresent formulae at the end of a cover letter seeking admission to one?
