My 15-year-old is also entering 10th grade, but I don’t think he knows it. We’ve been homeschooling since kindergarten, but don’t use schoolish conventions like grades.
My first advice would be to go for it. I was an energetic and intelligent student and high school only got in the way of my learning.

If you decide to homeschool, do a deep dive on Deschooling. I have some articles at DelawareDad.com. The basic idea is to analyze and clear out the assumptions trained into us (parent AND child) by the government education system. I took what I learned about deschooling and applied it to a broader set of assumptions I was living under. It changed my life: politics, philosophy, religion…everything changed.
The scary start looks like an extended summer vacation. For a teen, that’s going to be rocky and take some bravery on your part. The first idea is that we need time to gain space from the innumerable indignities of school. Think of it as taking time for yourself after a bad relationship.
Ask all your questions. Don’t worry about “success.” Worry about raising happy and healthy humans who can recognize their own needs and have the tools to fulfill those needs.
