Student Discount for Azure Fundamental Certification

Question

Im a student and I have already signed up with college provided email. Im interested to do the Azure Fundamental certification , even though I followed the steps in the "Student Discounts" page its not clear how to get the discount. By the way I have seen a service provider "Data Camp" which says they provide 50% discount for the same Azure Certification, need to know whether those credentials would be still valid.. TIA
