Background: The purpose of present study was to know the relation between the four blood groups (A, B, AB, and O) and high academic scores among students of Government medical colleges of North India. Materials and methods: Study was conducted in Department of Physiology, Dr BSA Medical College, Delhi and UCMS, Delhi on 247 medical students both males and females of age group 18-20 years. Blood groups were collected from past medical records during the time of admission and Confirmation was done during the blood grouping practical classes. Blood group, completion test marks, internal assessment marks (theory, practical and viva-voce) in percentage were tabulated. Statistical analysis was done by SPSS 16.0 software. Results: Out of 247 students 98 students were B group, 76 students were O group, 57 students were A group and 16 students were AB group. Total number of Blood group B students (N=22) who scored high marks were more than the other blood group students. While the %age of students of A blood group (29.8%) were more than other blood groups. Conclusion: Though our study showed that there was a variation in the academic scores between the blood groups A, B, O and AB, there was no significant association (p < 0.05) found between any blood group and academic scores. So, the conclusion of our study was that there was no real correlation between blood groups and academic scoring.
