Amen and amen! My husband and I share homework and exam preparation duties for our daughter (just because she's in school doesn't mean she stops learning when she gets home!) I am more than competent to teach English lit., American and European History, grammar, and rhetoric, but I can barely balance my checkbook. My husband is a Ga. Tech graduate in chemistry ("MIT - the Georgia Tech of the North") so he takes over for the sciences and all higher mathematics (as in "higher than 2 + 2"). She is studying Spanish (I mean, really, she has an in-house teacher for Latin, Greek, German, and Scots Gaelic, and she goes and chooses to study Spanish!) but I am actually able to assist her materially since it's a Romance language and the Latin cognates are all over the place. Don't ask me about endings or conjugations though!
