How does Mathongo got Data of 1.6lakh students??

like inke YT pe jisme inhone link di thi uspe to 80k views hai aur bohot kam percentage of bacche hote hain jo link pe click krke apni response sheet submit krenge unko...max 30k hi honge, to inke paas 1.6lakh ka data kha se aagya?? padhai ki charcha mein bhi yeh Anup sir ne bola tha ki 2.5k baccho ke 250 ke upr no. aarhe hain jbki 250 marks pe 150-200 rank bnti thi (ab unke dickriders bolenge ki unne sare QFTs ke count kie the to it was very stupid thing to do kuki sab unique bacche nhi hote har baar)... so is it just another fear moggering video? or am i worng at some point? edit- okay so calculator ki link bhi share hui hogi to i guess uski wajah se 1.6lakh ka data aagya hoga..ab pta nhi data repeat hua ya nhi idk....baaki ab 12feb ko hi dekhte hain result ky rhega....yeh kitni percentile aaegi ki bkchodi krna is time waste..sorry to disturb you all...bye
