What is the national ranking of graduate students majoring in HVAC in Dalian University of Technology? Is the exam difficult? What is the employment direction? How many people are recruited every year? What subject do you study? Dalian University of Technology ranks higher, and it is not difficult to take the 2 1 1 college employment exam.
