marks provisional mark is most likely the final mark. them changing it would be pretty damn small, unless you like inspected your exam or actually requested (with a fee attached) a formal re-mark.
the maths marks up there have alreadly been scaled/changed/fudged up whatever so yeah, don't hope think that'll you get higher, i'd say with 99% backing up that the mark you see there will so be the final mark you see in 7 days time.
well, yeah, probably what you didn't want to hear. but ehh, at least you know were you stand now.
cheers
