Not sure if this is a special limited time offer, but I noticed recently that Microsoft is offering two special “bundles” that are a significant savings for students.

The regular price of a Microsoft Azure exam is $165. That’s the price I paid for it. But now Microsoft is offering the exam, a retake voucher and a practice test for $99. That’s an unbelievable deal.
If you haven’t booked the test year, you might want to grab this. It appears you have 3 months to activate it and 1 year after that to take the test.
