In DC, I highly recommend going to the National Cathedral - religious or not - it is beautiful. The Wall is a shockingly peaceful yet hard hitting monument to visit.
Sounds like you have a great plan moving forward. Just an FYI, college algebra is essentially algebra 3, so it would be easier to CLEP it after completing high school math through algebra 2.
Good to know. We are going be using the Modern States College Algebra course before testing. Hopefully that will prepare her adequately. If not, we have no problem shifting gears 😊
