My parents are the authors of From Adam to Us. The answer to your question is "yes." You can start in Part 2 of any of Notgrass History curriculum. I would recommend reading the introduction, which is included in Part 1 and available for free on our website. We also highly recommend using the primary sources we compiled for each course. For From Adam to Us, that is the "Our Creative World" book. Let us know if you have any other questions.

We don't want anyone to be stuck with Notgrass if it's not working for you. We understand that our curriculum is not the best fit for every family. Here's our return policy: http://www.notgrass.com/notgrass/terms-conditions.html We ask you to return the books within a month or so after you start using the curriculum (not after purchase, as long as its the current edition). Even if you've started writing in the consumable books, you can get a refund, too. (Just return the cover of the consumable books and recycle the inside pages to save shipping.) You will have to pay for return shipping. Otherwise, you'll get a full refund of your original purchase price for the books. All the best, John

All Notgrass high school courses are written at a similar level. Our government and economics courses may be a bit more difficult because some of the content is more abstract and philosophical. On the other hand, if you use our world or American history courses as written, they involve more work--more literature and more primary sources and the Bible credit. You can access sample units from all of our courses on our website, and your son can read the ones from Exploring World History and Exploring America to see if they might be a better fit for him this year.

Hi, Susan. This is John from Notgrass History. I'm sorry that our website didn't clearly communicate where we were coming from in our understanding of Biblical history. Once you get past the early Old Testament portion of the study, I'd like to think that you won't find much that bothers you. But we do offer a full money-back guarantee, even if you've started using the curriculum. Please contact us through our website if you'd like to return it. All the best, John
