Hi, I want to create a quiz using infopath 2003. The quiz will have 10 questions each consisting of 4 options. Users will select 1 option. Each correct answer will have 1 point and at the end when users will submit the form then a pop up will be displayed showing the total score.Also at the end that form will be send as an email to some other user. Is this something which can be achived in as simple way as possible. If possible can i maintain an excel sheet which consist of all correct answers and lookup can be done using this excel sheet so that i dont have to hard code the answers in code?

I would not use a popup. Rather, just hide-show a section in the view with the total score in it. Sending email is easy. You can export all XMLs to Excel and report on that. It's a little manual, but definitely doable. No code needed.
