A popular combination may simply reflect timetable design, school supply or cohort size. Check your school's actual options, assessment strengths, workload and programme prerequisites before choosing.
The table describes uptake, not how universities count M1/M2. Counting rules vary by institution and programme and should be checked on current official admissions pages.
