Solution 3

Let relate to similar problems in real life, for example finding the second tallest students in the class, one way is:
1. Line them up from tallest to the shortest from left to right (ORDER BY[^])
2. Select the first two from the left (TOP[^]).
3. The shorter (MIN()[^]) of these two is your answer.

Solution 2

The second highest mark is the highest mark when the true highest mark excluded...

SQL

SELECT MAX(mark) FROM Student WHERE mark <> (SELECT MAX(mark) FROM Student)

Think about it...
