Dr Ahmad ibn Sulaymaan al-’Uraynee narrates :
One day, as he taught us ‘Aqeedah at the Faculty of Sharee’ah in Qaseem, he made us sit an exam; the exam was on a Sunday, and the following Saturday he brought in all our [marked] papers, considering the number of students was over 80. So, he handed out the papers and said:
“Read them [over] and whoever feels I have been unjust to him in the grading whilst marking, can come and see me.”
I recall one of the students went to see him querying half a mark and the Shaykh added that for him.
