Question

Hi I want to Develop a application Which will help To Check Answer Paper (objective Question). Answer Paper Will have Objective Questions. See Answer paper will contain some Bubbles like circle for each Option Suppose Q1 a() b() c() d() Q2 a() b() c() d() Q3 a() b() c() d() Q4 a() b() c() d() Student will Read Question paper And fill the bubble on answer paper. Suppose my answer to question 1 is C so i will fill that bubble with ink or mark it.. Now all the mark answer on answer paper should be scanned and should be recognized by software. and then compare with other values.

vERY basic one .. i Hope its a online OMR sheet .Then i consider those are radio buttons .. So what you need to do  simple create a array to store user selected values later store them in session variable just in case if OMR sheet is of 1+ pages just because upon redirection to next page the array variable can't hold the last page values were session variable can . Any issues will help you :)

You can ask the students to fill the whole bubble when answering different question. I think this should improve the accuracy for any OMR software you use.
