Hi Sana,

Hope you are doing well. Your question seems incomplete as you have not mentioned any specific exam. Some exams like GRE, GMAT, GATE, etc. have a validity of more than one year while most of the others do not. Therefore, your question could be better answered if you specify the exam.

Feel free to shoot any more doubts you might have.

Hello Student , Any entrance test result is taken over for the consecutive years or for the next year for admission  of any kind of courses in any of the colleges or universities in India.So if you are interested to take admission on the specific course on the specific College then you have  to appear again for the same entrance test for the next year or any year you wish to be.

For for more information click on the official website of the specific college.

Hope  this helps.
