Bumping this thread and doing a little parental bragging, so turn away if you are annoyed by this!
Kid #1 (going by age, not list of favorites...haha) is now 4 or so years into his Coast Guard career. He graduated high school through homeschooling. The only "normal" schooling he did was half of 9th and all of 10th and 11th, but in Moscow at the international school (thus not really "normal" as far as US public schools go).
Kid #2 just started his Air Force career in December; I was honored to commission him at my SIL's house back in May 2020 (he was ROTC in college, so they get commissioned upon graduation, but then don't enter active duty till later). He's currently training to be a pilot. He was homeschooled his whole life except for half of 7th, 8th-9th in Moscow, then 12th grade in Bishkek in an international school. Also not normal.
Kid #3 is a bit over two years into her Army career as a combat medic. She was homeschooled except for half of 4th, 5th-6th, 9th-10th in Bishkek. She didn't want to go back to the school in Moscow so she and my wife had a blast HSing in Moscow with all those museums and international book clubs and events and history etc. She graduated HS from the states though as we were one of the 60 families who got PNG'd out of Russia due to politics back in 2018.
Kid #4 is a senior in high school in our near-Boston town. She's the kid of ours with the fewest homeschool years and the most years of in-a-building schooling, half of 1st, 2nd-3rd in Moscow, 6th-7th in Bishkek, 8th-9th in Moscow, then when we got to the states she really wanted to go to a brick-and-mortar school, so she asked me for advice on how to approach mom on this. I suggested that mom responds to well thought out arguments. Our daughter did research for two days then approached mom, argued for herself attending the local high school, then the next day, my wife came to me: "Hey, Lucy proposed to go to the high school and I looked into it. It's a pretty good school so I told her okay."
She'll graduate this coming June.
My wife misses HSing badly, but she's a writer, so now she has more time for that, which makes her happy.
You're not a C1 (or B1 or whatever) if you haven't tested.
