Hi Ibrahim,
Thank you for contacting the Microsoft Community.
I truly understand your aspiration to become a certified Azure Data Engineer and your dedication towards achieving this goal is commendable. I am aware of the significance of taking this exam along with your discounts. Allow me to provide necessary details regarding this query.
Please be advised that vouchers are not stackable and must be redeemed one at a time, as only one voucher can be entered during the scheduling process. If in any case, you have earned these discounts by participating in a Challenge, you may check their terms and conditions.
Meanwhile, since you've mentioned that you are a student, you can be eligible for an academic discount. To avail yourself of this benefit, kindly follow the steps given in Identifying yourself as a student in your certification profile.
Once verified, a green check mark will appear on your Certification Profile. This will now allow you to take advantage of 30% off for fundamental exams (for all countries) and 45% off for role-based exams (excluding India and China). Since you are planning to take DP-203, which is role-based exam, you can avail 45% discount that will automatically be deducted in the check-out page.
If you qualify for a student discount, you can then add one of your voucher codes at the checkout page.
I hope this information is helpful. Should you have further inquiry or clarification, please don't hesitate to let me know.
