A survey called pre-test which has 70 questions

Each question has four options i.e radio buttons

e.g

1.High availability which is expected in technogoly

a. 9.9999%
b. 99.999%
c. 999.99%
d. .99999%

Suppose there are 3 users who have submitted the survey successfully
User1 select b option
User2 select a option
User3 select a option

And Correct Answer for this Question is "a" option
User selecting the correct answer will score 1 and rest users will score 0

So as per above example

User1 score 0
User2 score 1
User3 score 1


This i need to show in reports when we export the data.


How to do this....

Use Expression Manager to load an equation type question with the "score".

where that "a" option can i store in limesurvey

Means

The correct answer where can i save in limesurvey

Everytime a new survey is circulated to users will have different questions and different answers.

Then, you will need to use an additional equation question to store the correct answer value and reference that in the solution I provided above.
