Unlike many other national entrance exams, SNAP does not use a score normalization process. While there are three test sessions (SNAP 1, 2, and 3), SIU ensures that the difficulty level and spread of topics are statistically balanced across all three papers. Since there is no normalization, your raw score is directly used to calculate your percentile relative to the pool of candidates. For students appearing in multiple attempts, the best of the raw scores is selected for their final percentile.
