What kind of points does the law course in Oxford require (IB)

It's likely to be the standard offer published on the website, although in principle I believe colleges can set more specific and/or higher offers e.g. requiring a particular grade in a specific HL subject or similar. This is at least the case at Cambridge, although I'm not sure if this is all that common at Oxford.

I recently was invited to an interview by Pembroke College. I do the IB, and my predicted grades came out to be 40 points (6 English, 6 Econ, 7 History). If I do manage to get an offer, would it require the 38 point minimum listed on the universities website, or would it be more than this? Thanks
