     A simple program that I wrote using JSTL or Java Server Pages Standard Tag Library that will ask the user to give the grades in different subjects and then our program will compute the average of the five grades and determine whether the student pass or failed in their overall grades. The code is very simple and easy to understand. Add me at Facebook my address is jakerpomperada@gmail.com and jakerpomperada@yahoo.com My mobile number here in the Philippines is 09173084360
