@DadTwoGirls, note that some degrees at McGill will have an overall cost of around $30K. Also, the MacDonald campus of McGill tends to have small classes. Limited number of majors, though.
@hpcsa, India isn’t the only international option. There are some programs taught in English in Europe that are tuition-free.
There are also American colleges that are fairly cheap even for OOS, granted (total costs below $30K/year). Some are even pretty good like NM Tech, Truman State, and SD Mines.
In general, the Dakota publics tend to have low OOS costs.
