Why I perform SGP, Average, Total Marks or Ranking computed wrongly

System will compute SGP, Average, Total Marks or Ranking correctly only if the following procedures are followed:

1. Input students’ marks first and thereafter produce class ranking OR

2. If students’ marks are required to change after produce class ranking, the school teacher must change the students’ mark first and thereafter re-produce class ranking.

Many times the school teacher has forgotten to follow Procedure 2, ie to re-produce class ranking after changing students’ marks. Without doing so, the result enquiry will still effect the previous marks calculation instead of the latest subject marks as inputted by teacher. As such, the school teacher must re-produce class ranking whenever the students’ marks have been amended in order to compute SGP, Average, Total Marks or Ranking based on latest input marks.
