Congratulations. Take it and run with it; as Harriet Vane points out in Gaudy Night, whatever else happens in your life, no-one can take a First from you (and don't bother with the "just barely scraped" thing - I know the impulse but look at it this way - the last Test match ended with the parties 15 runs apart on an contested wicket. The margin and the contest are quite interesting to statisticians, but the result is what matters in the end.
