Questions about homeschooling my younger sister?

You will have to teach her English, math, social studies, a foreign language and science. You had better start now embling all the resources you will need to teach those cles. You will need lesson plans and materials. There are sites online where you can get a lot of these, and there are teacher supply stores. The problem with the stores is, they deal mainly with elementary grades, so you're going to have to scramble to get high school materials, so start today. When your sister gets back, she will have to submit her previous transcripts and take the SAT and any other entrance exams to get into college if she wants to go. I'm afraid big sister's remarks won't count for too much.
