We considering the homeschooling for my son but I don't have any knowledge. So I asked the school but they also don't have much idea what should we do.

So the main question is,
a. Is it possible to withdraw high school now and join a homeschooling middle of the school year?
b. Is it possible to transfer the credit from homeschooling to high school after 2 or 3 months later?

Any recommendation or suggestion would be very helpful for us and I really appreciate that.

Thank you,
