Most schools charge the same regardless of major. At my university (private) full time was 15 credits (3 credits per class). As an engineering major, I shouldered a 21 credit per semester course load for all 4 years. Payed the exact same. So yes much cheaper for an engineering major. Add in the factor of real world skills and it's a downright bargain.
