So if you have to make them up, you can\u00a0<s>either<\/s>\u00a0come to any of my office hours in the Math Center\u00a0<s>or schedule a time (e.g., 7:30\u20147:50 pm) to join my personal zoom room with your camera on.

Note if I write &#8220;Math 129 quiz makeup&#8221; on my calendar, that means this time slot has been reserved by some student (of course I never include their names there).<\/s><\/p>\n<p>Note that Professor Emerson announced that\u00a0<span class=\"il\">all<\/span>\u00a0<span class=\"il\">quiz<\/span>\u00a0makeups after the second midterm must be done in person instead of over Zoom.
