Do these letters have to be especially for the Scholarship or would you accept letters of general reference, because I already have a couple.

The reference/recommendation letters must be recent and they must refer in particular to your eligibility for this scholarship and your aptness to attend a Course in Modern Greek language. Letters that are outdated or are non-specific they are unlikely to bear a strong recommendation to your case. Also, letters that are older than one year will not be accepted at all.
