From the author - "These daily instructions were written to aid my own children as we used the Apologia courses. During our first year, we weren’t sure how much to read daily to complete the book by year’s end. You can’t simply divide the number of pages by days due to labs, study guides, tests, etc. We also had too many days of labs with no supplies on hand."
These lesson plans for Apologia's Exploring Creation with Biology (2nd ed) will direct your student as to exactly what needs to be done each day and will list needed lab supplies in advance. Using this guide, it takes 165 days to complete the course.
