Starr.........great news!!!! How exciting!
On the slim chance this is applicable(there is a branch of the same university my daughter attends in our area): My daughter is in college now,like yours is. I found out from a friend of hers that her university has a special multi-student rate (that I did not read about in any literature!) that if there is more than one family member enrolled at the same time,the tuition charge is halved for the second student! Like others posted,there may be other "special" rates,etc for the taking so be sure to check all options. It never hurts to ask!
Best of luck and sounds like you will be busy with all this during "winter-layoff".
p.s. My kids tested poorly in math,too and were put in a class that took that into account. (Me,too,35yrs ago!) Like I told them.....with a class like that (although to do the best that they could) you just have to pass it,not set the math-world on fire!
