Hello one-line quoter :p

Wasn't optimization exactly, but it was far less redundant than the original :p

totally rubish code....anyone who is appearing for this test can find the answers for each question in page source code. My suggestion for the code will be to create a table with columns
1) Question
2) OptionA
3) OptionB
4) OptionC
5) OptionD
6) OptionE
7) Answer
8) QuestionID
9) Level (optional if want to have a level Master table also)

Fetch each question from the table and on submiting form check if Answer submitted by user matches with the answer for that particular QuestionID.
