Good evening all. I'm looking into getting the Basics of Biblical Greek Grammar and Textbook. However, being the dirt cheap nut that I am, I go looking for used. I found the first edition grammar and the second edition workbook for under $15 each. Happy day, until I hit upon the question I'm about to ask you. Are these two would be compatible with one another? If so, great. If not...I can't use them. Thanks in advance.
