finishing MATH220 April 2011

Hi,

I've already ranked that exam as complete, but it isn't 100% fair since we still need to deal with the hint you rated QBH. I made some modifications, please have a look so that we can wrap-up with that exam asap. Cheers,

I finished the QBH, made some more minor modifications, and then flagged it as good. I'm happy another exam is done. It was fun finishing that together this morning :)

Indeed! thanks!
