Cheating In Jee Mains

Actually my one of the friend in coaching... Exam se 3 din pehle Jo test hua tha usme uske only 30ish/300 aaye the aur jo topper tha uske 176/300 ( allen ke test tough hai) ... Yahi nhi ham dono 10th se sath mein the har exams mein use teachers separate bithate the kyuki vo hamesha dusro ke papers mein ans dekhta tha and guess what....!!!! Topper ke 99.214.. Us ladke ke 99.34576 hai

Jo Banda pure saal padhai nhi, ek bhi tests mein uske 150 bhi cross nhi hua and pure coaching mein aawaro ki tarah pure din ghumta tha.. usko 99.3???? Kaise???
