Grade labels suggest a starting level. School sequences vary, especially in high school; use the prerequisites and choose a different grade when it fits better. The curriculum map explains coverage and limits.
Lessons and tests support independent study and school learning. They do not award school credit or establish that local school or home-education requirements have been met. Younger learners can work with an adult reading aloud, drawing or discussing answers.
Guest answers are temporary. Keep your own work or download your practice notes before leaving. Nothing here sends school grades to a teacher.
