The sum of $3$ odd numbers is an odd number.  The sum of $4$ even numbers is an even number.  The sum of an odd number and an even number is an odd number, so the total score of the $7$ students is an odd number.  The total score of $8$ students is an even number, and the sum of $2$ odd numbers is an even number.  Therefore, the score of the last one should be an odd number.
