Yes, that’s generally the case. The complication is how each school of architecture defines its own exceptions. There is little consistency (and sometimes little rationale) from program to program, or even student to student.
From one MArch admissions page:
The issue that @bgbg4us describes about her daughter’s difficulty in getting credit for her high school calculus course is a good example, though luckily she got a ruling in advance. My son had a similar issue with a physics class he took as an undergraduate, because the course was titled something like “Everyday Physics.” Eventually he prevailed, but it entailed a lot of back and forth between the gatekeepers and the undergraduate college.
Other points of differentiation from MArch to MArch include summer sessions, thesis semesters, work-study, study abroad and study away (e.g. in New York) programs, advance placement, course equivalency, “electives” that are actually required plus all sorts of fine print that can expand or contract the time and money spent completing the degree. So even though the architecture board specifies the MArch’s basic curriculum, each school adds and refines to reflect their own priorities.
