Hi! My son is graduating this year and I asked him if he'd like to study to become a certified bookkeeper with me. I told him I would pay for the books, we are just responsible for our own exams. That way we can share the books and study together and save the cost of buying two sets of books. Is this okay to do? Or is there something in the books that we'll each need our own copy for? I've been a stay at home mom for 18 years, so I'm excited to start a new venture. Completely new to this, so any tips to help out would be greatly appreciated! Thank you!
