Prizes were given to the top 8 pupils. Gwen won a prize. What was the lowest she could have scored?

1. Count the number of pupils starting from the highest score to find the top 8 pupils.

Number of pupils scoring $100$: $1$
Number of pupils scoring $98$: $2$ (Total: $1 + 2 = 3$)
Number of pupils scoring $95$: $3$ (Total: $3 + 3 = 6$)
Number of pupils scoring $91$: $2$ (Total: $6 + 2 = 8$)

2. Identify the lowest score among the top 8 pupils.

The top 8 pupils scored $100$, $98$, $95$, and $91$. The lowest score among them is $91$.
