Drexel Admission

I am thinking to apply to Drexel for Spring 2018. I just love Philly. I checked fees for Drexel and it was almost around $87k a year. The tuition alone was $17000 each quarter. Is Drexel really so expensive? The tuition seems way too much to me. Is it an exaggerated amount? If so, how do they charge each quarter? Is the tuition fee based on credit hours taken? I read somewhere that they charge $1024 for each credit hour taken. Is there someone out there (maybe current student) who can help me out here.
