<em>SQL Query</em>
//////////////////////////////////////////////////////////////////////////////////////////////////
select student_name from Student
INNER JOIN Class ON Student.id = Class.student_id
LEFT JOIN Instructor ON Class.instructor_id = Instructor.id
WHERE Instructor.school <> 'Computer Science'
Explanation:
First thing is to select the student_name from <em>Student</em> table.

Next we need to connect the <em>Class</em> table with the <em>Instructor</em> table, to get all of the Instructors currently teaching class(s).
Finally, we place the Where condition for the acquired instructors to not be from the Computer Science department.
