Online question answering system
Mainly do single-choice and multiple-choice questions! I put the questions, options and correct answers into the same database, three questions! !
Can I design the option as a field and store it in json? Are the answers stored in another field?
When the user answers the question, I return all the questions, options and answers. When the user selects the answer, how should I judge whether the answer selected by the user is correct? Or do we need to request the database for the answer?
