At the west gate of University of Mining and Technology, you can take bus No.2 (westbound) and get there in a few minutes (get off at Cai Xiao Station).

Or take bus No.69 at the west gate of Mine University and get there in a few minutes (get off at Financial School Station).

It's very close, and it will take about 10 minutes.

I hope it helps you.

Good luck in the exam.
