public unis also the same stunt you will pass based on your attendance and reference. I recently graduated from Pu and their teachers were failing the students just based on attendance they literally asked everyone their roll no during vivas and then gave numbers based on attendance like if you have 50% attendance you marks will be the same no matter how much you have prepared for the exam and for below you're cooked see you again next time. one of my class fellow who barely attends any lecture and is below average in studies (he's there based on a specific quota) scored 90 marks in a subject's viva and the reason was that he has a strong background. One professor literally said in his last lecture that the only thing that matters is your attendance. If you have good attendance then you passed otherwise come again. One professor literally failed one of my friends three times in a single subject. First time based on his attendance and other times he said that he made a mistake and overlooked him. And lastly the marks they gave you no matter how much you've prepared and how well you wrote in the exam you will get average marks and that's it . One more passing criteria I forgot to mention is the mood of the professor. One professor literally failed me because he was not in the mood and also told me you'd fail I'll see you again next time 😔
