This is exactly what I used with my kids. Neither finished the entire course of 100, because they preferred to go to YA novels rather than the structured practice in the later lessons. Both have consistently tested at multiple grade-levels of reading ability above their public school age cohort. I think I started them at 3 years old, though it took a while to get some traction. You might have to repeat some early lessons.
