Computer Based Testing / assessment system

Looking for the right PHP script

[Stenness]

Dear friends,
One of my clients would need an online Computer Based Testing (CBT) / assessment system. Basically, he needs a software able to present a series of questions (in Italian) with multiple choices and capable of calculate the cumulative score for multiple answers, with the option of sending the result of the test to the admin. The UI should retain the same look of the main website, so a separate header/footer management may be needed. The presence of a security system to access the tests based on the check of the IP addresses would be also useful.
I've looked for hours on the net for some PHP-based scripts, and the best one I found is TCExam. Unfortunately, this software requires PHP 5 and my shared Unix server runs PHP 4.4.2 only.
Does anybody know of any other software / script offering the features I mentioned above?

Any help would be greatly appreciated!

Hello,

I would check the script repositories for something that matches your needs:

• hotscripts [hotscripts.com]
  
• sourceforge [sourceforge.net]
  

Good luck!

P.S. If it doesn't need to be within your site, I know people who are ridiculously obsessed with quia.com

Thanks for the tips, but I had already checked the script repositories - I was looking for something more specific, possibly from someone with first hand experience with one of those scripts.
