oxford的两封推荐信是两封academic好还是一封academic一封professional好啊？

看了官网的要求感觉没有什么指向性

Two academic or professional references submitted via the online application form.  

If you are in the process of completing a degree programme one reference should be from your current institution
We require references to come from a valid institutional or professional email address; we will not accept a reference from a gmail/hotmail (or similar) address.



谢谢各位！！
