OCR 21st Century Science CA grade boundaries

Hello, i was wondering if anyone knows what the grade boundaries are for the triple science controlled assessments. They are the ones that are out of 64 raw marks.

As of 2013 Jan.
The trouble with this is that UMS boundaries for grades remain the same, but the number of raw marks you need to attain to get the UMS varies from year to year.

You can't know, not until after the exam has been taken.
The UMS/Raw score conversion is dependent on the year. If everyone gets 100% raw score, apart from one person who got 99%, the 99% would equate to very low UMS.
An extreme case, granted, but do you see the point?
