Inevitably, there are changes to the products featured among my Top Picks after the book has been published. Brief descriptions of such changes appear below. If changes are significant enough, I will direct you to a revised version of my review that is available on my website.
Apologia Science (Exploring Creation series)
When the first printing of the third edition of Exploring Creation with Chemistry came out, it was significantly revised from the second edition, and it ended up with a number of errors. As of May 2015, Apologia has made available Exploring Creation with Chemistry, third edition, second printing in which they have corrected the errors. This is the edition you should look for.
Berean Builder Science series
A third volume has been added to this series: Science in the Scientific Revolution. It is reviewed here.
BJU Press Science series
The third editions of this series were reviewed for inclusion in 102 Top Picks. New fourth editions that are now available for grades four through six are very similar in content, but you still need teacher's editions and activity manuals that are the same edition as your text.
Complete Curriculum no longer sells their membership option, but you can still download textbooks. Downloads are now available only through Educents.
(Updates reflect the expansion of the courses available for high school level.)
Easy Peasy is a free online homeschool curriculum for preschool through high school, generously shared by a homeschooling mom named Lee Giles. More is added to the curriculum as she completes additional course plans. It is well on its way to eventually being a complete college prep program covering all of the way through high school....
Giles has also created a separate site for high school level at www.allinonehighschool.com. There are four years’ worth of courses for math, language arts, and science. Three years can be covered with courses for Bible, history, and physical education/health. The growing number of electives include such as courses as art appreciation, music appreciation, and three years of Spanish. Courses continue to use online resources such as courses from Georgia Virtual Learning and CK12, so no textbooks need to be purchased. While Giles has created some of the high school lessons, Easy Peasy fans have contributed others.
Essentials in Writing
Essentials in Writing was originally offered as a set of DVDs with a PDF file for the worktext for each course. Worktexts are now available only in printed format along with the DVDs.
God's Design Science
God's Design Science is now available in the fourth edition. The content is updated but remains very similar. The age range covered for all books has been narrowed to grades three through eight. Resources formerly available on a CD-ROM are now free digital downloads.
Language Lessons for Today
My Father’s World has published three more books in their Language Lessons for Today series. See my updated review which includes all five books.
Math Mammoth has now added a seventh grade pre-algebra course.
Math Without Borders
David Chandler has just added a Calculus course to his Math Without Borders Home Study Companions series. Prices for each Home Study Companion are now $79 each.
Michael Clay Thompson Language Arts Courses
I have revised the section of this review regarding MCT Literature courses since two new courses are now available, and their use in conjunction with other MCT courses has been slightly rearranged. See the revised section in my review.
The World of Animals
The World of Animals edition co-published by My Father's World has unfortunately gone out of print.
