I would like to introduce you a new site which is very useful for taking exams and quiz for all grades. The exercises on the site is online and interactive and that is totally free.
The quiz site is designed for taking tests from Grade 1 to Grade 9 with different exercises and quizzes from Math to Spelling. The students can immediately get their score and feedback.
The site is a new site and needs improving, but the currents exercises and quiz are really fantastic.
I think you should at least give it a try and experience it. Thanks
