Wordpress Exam Plugin

Good Day I have the website Altimetro2992.com. This website is for spanish airplane instruction. I need a plugin in which users practice their skills trough exams. In aviation in order to get a license you need to make a written exam, these exams are taken from a question database. The purpose of these plugin is to help students in their carrier by practicing the questions in a test format. Please take a look at exams4pilots.org. I really encourage you to take a exam so you can see what I need. Because I basically need the same thing. Pleace take this example for reference 3268 (Refer to figure 4.) Which color identifies the never-exceed speed? A) Upper limit of the white arc. B) The red radial line. C) Lower limit of the yellow arc. What do I need from these plugin? I divide my needs in three sections: Before Exam, During Exam, and After exam Before Exam: 1) Offer different types of exams (private pilot, Commercial Pilot….) that can be selected using a “change” button. 2) Also user may decide which subjects they want to evaluate (weather, aerodynamics, weight and balance). 3) Allow user to decide the number of questions for the exam they are about to take. 4) The format of the exam needs to be “Printer Friendly” During Exam: 1) Each question must have a Question ID, these ID will identify the question inside the plugin and when the exam is been made. (if you take an exam on [login to view URL] you can see that each question has a big black number, that’s what I mean) 2) Questions may have “figures”. So when Iam making each question I must have an option to put a figure into the question as a link. After Exam 1) the exam must have a time limit. When the time is done, the exam will grade It automatically. 2) The questions that where wrong must be display marking the correct answer and a explanation of how is done. This explanation will be written and a video. Pleace take [login to view URL] as an example if you take an exam you can see what I want. This project is for wordpress, so i need it all this to be in a plugin. For further questions pleace contact me! . Thanks
