Oh, sorry, I misread based on their saying that their costs run less than the 38K average total cost for publics in MA, but I guess in-state must be included in that average. Yeah, looks like about 45K minus merit. Still cheaper than the Amherst flagship as a baseline, and chances of merit are much better at Lowell than Amherst for any given candidate. If Lowell doesn’t add up, I don’t see how Amherst does.
TBH, the truly affordable programs are in the midwest, not on the coasts. There’s good CS at highly affordable and high-quality schools like South Dakota Mines - they’re just not popular because they don’t have an in-demand location. For 26K/year (before any merit - I’m not sure whether there’s merit $ for intl students or not), they offer an excellent STEM education, and they have a robotics minor as well. http://ecatalog.sdsmt.edu/preview_program.php?catoid=13&poid=974&returnto=2327 U of Minnesota Morris also has a solid CS program and a sticker price of around 25K/year (with the possibility of internal transfer to the Twin Cities flagship campus - but the yearly cost there is about double). That’s about as inexpensive as it gets, short of attending a US community college for the first two years, which a fair number of international students also do.
