A 350 (2006) 174] is analyzed and\nit is found that this protocol is secure for any eavesdropper except for the\n\"students\" who take part in the exam. Specifically, any student can steal other\nexaminees\u0027 solutions and then cheat in the exam. Furthermore, a possible\nimprovement of this protocol is presented.",
