Oxford submitted work

Is it okay to submit AS work? And can you submit exam scripts? (English essays for ab initio Russian)

The guidelines ([1] [2]) say that it must be "recent" and that it should "demonstrate your analytical, reasoning, language and writing skills.". So I'd have thought that AS work is fine if you think it does the best job of showcasing your abilities. The guidelines also say "It must be original school or college work, marked by a teacher, and not re-written or corrected in any way". The way I'd interpret that is that exam scripts are not acceptable, but I'm honestly not sure so you may wish to email them.
