Write a SQL query to get the second largest AvgMark from the “Student” table. You are NOT allowed to use row_number(), rownum or rank() or limit.

Sure, here's a SQL query to get the second largest AvgMark from the “Student” table without using row_number(), rownum, rank() or limit:

SELECT MAX(AvgMark) AS SecondLargestAvgMark 
FROM Student 
WHERE AvgMark < 
    (SELECT MAX(AvgMark) FROM Student)

This query first finds the maximum AvgMark in the Student table using a subquery, and then selects the maximum AvgMark that is less than the maximum AvgMark found in the subquery. This will give us the second largest AvgMark in the table.
