Admission test proxy?

Admission tests are going on in public universities. Students having passed H.S.C are participating in those admission ordeal. They (candidates) are studying heart and soul after the HSC exams and doing everything that is needed to win this battle. And PROXY is one of unfair ways to overcome the ordeal.
Students of various public universities are participating in exams for other candidates to help him/her to pass the admission test. To do this, the candidates buy admission forms in a serial or roll number. And the candidate is seated beside the university student to steal some answers from him/her.
Now-a-days this 'proxy' culture seems to be nothing to the students. But here some other students who deserve admission are being deprived.
Will the university authorities do something about it?
