online exam system

[aspbeginner]

Am currently working on my end of semester project (online examination system )where questions are to be obtained from a database. The question is displayed in a label and the four options in radiobuttons.. this form has 3 buttons that can enable a user to navigate to the next question,previuos question(s) and another to intentionally end the exam.whenever a user clicks on the back button of the form to access a previously answered question,the previous question is shown but the radio button that was checked as the answer is not checked.Any idea on how can i maintain the checked status for the previously answered questions?

Keep the answers in database or Session

can you store the test data in a cookie and write the buttons with an if statement? Similar to my post on this page?

If you collect the answers in a cookie as you go, you should be able to redirect based on the cookie parameter. So if the cookie parameter is something like "if cookie[question4] is null or empty then redirect to question 3" ??? This would also allow the user to skip a question and go back to it at anytime with a little more logic.

Please help!!! It is urgent...

[Mamata sahoo]

sir good afternoon.plz help me, how randomly taking two questions from each five groups or catogory ?Total question should be ten.what is the code?

[Rajini Yella]

1. Load the questions into an array.

2. Call a random number generator (http://us2.php.net/rand) to select questions from the array.

3. As each question is selected, load the selected questions into a separate array.

4. Each time the random number generator is called, check the "selected questions" array to see if that question has already been used. If so, go back to Step 2 to select another question.

Repeat until the desired number of questions have been selected.
