This work was aimed at assessing one of the examinations applied to the students enrolled in courses of Biochemistry and Molecular Biology at the School of Medicine, UNAM. We analyzed a final examination in this subject. The test consisted of 80 multiple choice questions. The database was exported to Excel® and then to the SPSS16 statistical software for statistical analyses. The following techniques were used: (1) dificulty index (Pi), (2) discrimination index (Di), (3) discrimination coefficient (rpbis), and (4) Cronbach’s alpha. Those questions that complied with 3 of the 4 mentioned techniques were considered acceptable; of the 80 questions, only 25 were accepted corresponding to 31%. The topic with the largest number of accepted questions was Water and pH (75%), and the topics without accepted questions were Bioenergetics and Hormones (0%). It is recommended that the faculty members that elaborate multiple choice examinations must know the subject, and should have a formation in didactics and educational methodology.
