It’s never encouraging to look into your pigeon hole and see a slim envelope from a scholarship committee: in this case, the selection committee for Oxford’s Overseas Research Scholarship (ORS):
I regret to tell you that your application was unsuccessful. Unfortunately, due to the large number of applicants we are unable to provide individual feedback on the results.
Those who have applied and not found such a letter in your post, take heart. The ORS is quite a nice scholarship, which converts the fees you pay as an international student to those paid by someone from the UK: a dramatic reduction.
