We will review the exam and you will account for your having obtained your copy of Mere Christianity in class on Wed. 3rd January, 2008.
If you have it and wish to get a step ahead, read the Preface. Be sure you have a Mere Christianity section in your notebook.
You may have a used copy, it may be from a older sibling, or brand new, the edition doesn't matter (because we will refer to and cite quotes by book, chapter and paragraph, not by page). They are available in the school bookstore and at bookstores in town.
