Hi We are cleaning out our closets this year as a goal! Our kids have moved on in sizes and activities they enjoy. Hope you enjoy these items many new with tags the kids grew out of or didn't use. Although eBay gives us more time, we try to ship the next day when possible. We hope you enjoy our items and get good use out of them! Many of our adult clothing items are new or barely used due to size changes and occupation changes.
I looked over this and it looked like great content for any kid wanting to pursue the sciences. I am more of an old school Math person. I don't believe learning all the definitions will get you where you need to go. Quick ship and I like the extra workbook and answer key so I can help my daughter do problems outside the class, they aren't doing in the class. Her class is only using the textbook ( which may be delayed due to COVID ) but a nice product for a homeschooler, advanced Math student or coop math group.
