Georgy Kotsaga's former classmates from Singapore Management University's Juris Doctor (JD) programme said he could have acted out of stress or fear of being unable to practise law here.
In a Facebook post on Tuesday which has since been taken down, Ms Michelle Wong said: "I do not approve of his action but I understand his state of mind because all of us in the JD programme are subject to a fair amount of pressure."
The programme, which costs about $70,000, is for those with a bachelor's degree in other disciplines or a law degree from countries following the civil law. Singapore follows the English common law system.
Students need a minimum grade point average (GPA) of 3.0 out of 4.0 - equivalent to a B grade - to practise law here. They also need to do six weeks of internship and 50 hours of community service. A court heard that Kotsaga's actions were driven by fears that his 3.09 GPA would fall below 3.0 after the exam.
Mr Christopher Ng, 41, wrote in a blog post on Wednesday: "Georgy barely made that cut and my speculation is that the fear that he would not be allowed to practise led to him to... delete all our scripts."
