My personal placement suggests that I do not skip introductory macro. Can I just go ahead and skip introductory macro?

No. You may not skip introductory macro unless your personal placement recommends it or you have permission of the DUS. If you think this placement is in error, please first read the placement guidelines above, and then (if you still think the placement is an error) contact the DUS. Please bring with you relevant documentation about the courses you have taken and your scores in those courses.
