Having a problem in an online exam result
For now everything is ok, user take exam and get the result immediately after the exam.
The result for each Q has the Q’s title, Q’s body and user mistakes.
Problem is about when the user want to check the exam result after for ex. 2 weeks and after this 2 weeks some Qs maybe has change, some new questions adds and some Qs were removed!
what should i do? how to solve the problem?
thanks in advanced
