Lifepac history and science 1st grade level

I’ve been looking for a science and social studies/history curriculum for my daughter for next year. She will be 5 in november so she is technically a preschooler however we are completing kindergarten level curriculum this year. We will be starting upper level kinder and 1st grade material next year. I am looking into using lifepac history and science curriculum at the 1st grade level. I read over the description of what topics and skills are taught and I think she would do well with it. I’m not sure though. I don’t want it to be too far over her head. Has anyone used this specific curriculum? Thoughts? Opinions?
