@JesseJune , with all due respect to ex2x01, who is not a current or past student at Maryland, I would consider the comments of the other responders (who are current parents) to be a more accurate assessment of the situation with the mold and how the school is handling it. The reality is that if you look into most any school, you can find incidents of illnesses, threats, suicides, and other horrible situations.
Maryland is a fabulous school for engineering and provides a great balance of academics with amazing opportunities as well as a really good social life - which is honestly of critical importance to engineering students since they need some balance for the extremely challenging academic demands. My son got his undergrad in MechE at Maryland and also got a Masters. He absolutely loved it there.
For Aerospace in particular, Maryland offers the unique opportunity to do research in a neutral buoyancy environment - no other university has this. https://research.umd.edu/core-facilities/nbrf In fact, NASA uses Maryland’s facility to do research there and NASA Goddard Space Flight Center is about a 10-15 minute drive from campus.
Fwiw, here’s the postings about the mold http://reslife.umd.edu/moldconcerns/ but the multi-year strategy won’t be announced until the end of January.
As for engineering at Maryland, I hope you find this thread I made a few years ago helpful (while the stats listed in the beginning of the thread are outdated, they still provide some useful insights) http://talk.collegeconfidential.com/university-maryland-college-park/1732708-everything-you-want-to-know-about-engineering-at-maryland-p1.html
