Professor Maca is knowledgeable and extremely fair. If you are into Mayan culture (and particularly the site at Copan), you've struck gold. Slides everyday AND intense notetaking was required. The quizzes are easy if you study the terms. (Easy to ace if you put the time. ) Professor "Mac" is passionate and was always available. Gave opportunities for making up credits by writing extra papers, working in the lab, or attending guest lectures. Professor Maca's greatest quality is his sincerity. Take his class if he comes back to Columbia!
