Women's/Liberal Arts Colleges not technical enough?

The “running out of classes” problem is more common, but not exclusive, at small schools due to a tendency toward smaller departments. However, each school is different, so checking each school’s offerings (in catalogs and schedules) to see if “running out of classes” is a risk in each department of interest is something that can be done early in the search process. Cross-registration agreements that are convenient (e.g. MH or Smith with UMass) can help.
