Prometric is offering 15% or 20%, or 25% off on selected Microsoft certification exams. The lower level Technology Specialist (TS) exams are getting the 15% or 20% discount, while the I.T. Professional exams are getting the 25% discount.
This is certainly better than paying the full $125.00 exam fee. I firmly believe that passing the exams for whatever you specialize in is a good idea to help build and maintain your career.
