    Hello! Thanks for the lesson it's the best lesson I've ever seen. But I've some questions. It was cool if you can explain to me some points or give me advice about where I can find information about it.

    I start create the database for the Online Examination System in PHP and I use the databse from your source code like sample. Now I've created the admin_table. It's clear. But in your admin_table there is indexes for admin_id I'm not strong at MYSQL but I want to boost my knowledges. So, can you explain to me what the indexes means and why to use it. Thanks

      This one works out.
      in ajax_action.php there is a if statement
      if($_POST['page'] = 'question')
      which should be
      if($_POST['page'] == 'question')
      change it it will work

    In updated version there is no option of user/ admin registration on the login page hence I have added the student and user(admin) data manually in the database. But after doing so I am still unable to login as Admin or student. I am a bit confused as I am not getting any error message after entering the student/admin email and password. It just get stuck on that page.

    Thanks for all but I have a problem that:
    some participants (as I think) after they do the exam and after they arrive to the last question maybe again, they check their answer so the system register second entries for the same question so as a result
    I found after the exam some of them have (Marks) more than the question total number.
    for example, the question is 25 but the Marks are 37 (if all answer are correct, they will get 25 Mark (1 Mark for each question).
    There is a missing code as I think which does not allow the duplicate answer entry for the same question in this table
    user_exam_question_answer.
    Who has the solution?
    Thanks
