* शुल्क रियायत (Shulk Riyaayat): This is another formal option that emphasizes the reduction or discount on the fee.
Informal:
* फीस में छूट (Fees mein chhoot): This is a more casual way to say "fee concession".
In a sentence:
* मुझे स्कूल की फीस में छूट मिली। (Mujhe school ki fees mein chhoot mili.) - I got a fee concession from the school.
* मेरे बेटे को शुल्क रियायत दी गई है। (Mere bete ko shulk riyaayat di gai hai.) - My son has been given a fee concession.
You can also use "शुल्क माफी (Shulk Maafi)" to specifically request a complete waiver of the fee, but it's less commonly used in general discussions about fee concessions.
Remember to choose the wording that best suits the situation and audience.
