i have tried this array method.

i don't know how to put the questions and respective options in one table and answer key in another table and then display questions.

i want that questions and their 4 options should come from database in random but non repeated order.
and once test is over then the user can get the correct option and the explanation for the same way the questions came.

so please can you give the code for the same.

No, because that's not how it works: We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Have a think about it, and about what you need to do to ensure a non-repeating sequence. Hint: random numbers are just that: random. So you need to generate a list of questions in advance, store it somewhere, and fetch a question at a time from it. Is there anywhere you can store information in Javascript across page boundaries?

If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!
