Do you know what median and mean are?
The median is the middle number. So if you have 5 students in your class and they got 30,45,65,70,90 then the median is 65%. In your case the median was 59% so half the class got below 59%. Since Andrew mark is 62% its greater than half the class so he is in the top half of the class
