To be in the top 5%, a student's score would need to be greater than 1.645 standard deviations above the mean (since the top 5% is the area in the upper tail of a normal distribution with a mean of 1000 and standard deviation of 200).

Thus, the lowest possible score a student needs to qualify for acceptance into the university is:

1000 + 1.645(200) = 1330
