Myself praveen g [[protected]]. I'm pursuing b. Tech it final year in rathinam technical campus, coimbatore.in my 6th semester, i got arrear in artificial intelligence (Cs6659) paper. I applied for revaluation and got the result as no change. So i applied for review of paper (Challenge).in that, i got cleared in that paper with 'c' grade. As per rule if got cleared in review the amount i paid (Rs. 3000) should be refunded. But still, now i didn't receive my money. It's almost going to be a year of time, but yet to receive my amount. So kindly do the needful things as soon as possible to refund my money.
Thank you!.
