Build an "Online test series" Website

Build a website for "online practice tests" for an exam called GATE (an entrance for Post-Graduation in Engineering in India). The website should be extremely clean and simple. It should have the following things: 1. I will provide userID and password to people (So, there should be a mechanism to activate and deactivate userIDs and passwords according to my will) 2. There will be 20-25 question papers, (objective and/or numerical answer types). When people write these exams, they should be timed, and as soon as they complete the question paper, they should be given the result. This means, there should be auto-correction (should be easy as the answers are pre-fed). 3. The original GATE exam mock can be found here: [login to view URL]@@181# So, I want the exams on our website absolutely looking similar and having same experience. The website will have following pages: 1. Home page: Detailing our test series and details like fees etc., 2. About Us 3. Student Log-in : For people who are assigned userID and passwords - This page, once logged-in, should take them to their exam profiles (Exam profiles should have record of previous exam marks and once they click on any of their previous exam, it should give details like their answers, marks etc.,) 4. Contact-us: Simple details of our Email and Phone nos.
