ARGH!!!! Undoing equations with rounding makes my head hurt.

I've spent much of the morning and the entire afternoon working on the Freshman Scholarship Calculator for the Baylor web site. The trouble is not in calculating the actual scholarship, it is in calculating the little hint on how to improve your scholarship or how to become eleigible for a scholarship. The combination of rounding and certain obscure rules, make this way more difficult than it looks. The 2006 version of the calculator has been up for months. Right now, I'm trying to finish up the last bits on the version for the 2007 year. Maybe tomorrow will be a better day.
