Hello Yashwanth,

INR is the short form for Indian Rupees. It is difficult to tell you whether it is monthly or yearly without any context, it will depend on the Institution, do provide some details in the comment section if you want to know accurately. If it mentions p.a or per annum then it will be yearly. If it mentions semester wise then in every six months you will have to pay.

Hope this answers your query, feel free to ask for more info.
