! Two examination papers are written at the end of the course.
! The final mark is either the average of the two papers, or
! the average of the two papers and the class record mark (all
! weighted equally), whichever is the higher.  The program 
! should reads in the class record mark and the marks of the
! papers, computes the average, and shows PASS (>= 50%) or
! FAIL (< 50%).
