CalTech vs JHU BME vs GeorgiaTech

While the admit rate was 37% for GT instate, I am baffled as to why anyone would think that is a problem. GT used to have a much higher rate of acceptance than this and the school is still the same school just as many schools admit rates have decline substantially. Did these schools suddenly hire different professors and develop new curriculum? No. And by the way GT has always been a self selecting university as it is highly quantitative and rigorous. It was an insulting remark for the students of Georgia.
