Candidates have the option to attempt SNAP up to three times in one year. You must decide which dates you want to appear for at the time of registration. If you appear for more than one test, the system automatically picks the highest score you achieved among all attempts. For example, if you score 35, 42, and 38 in three attempts respectively, your final percentile will be calculated based on the score of 42. You do not need to 'choose' the best score yourself; the university handles it.
