Score answer depends on fastness

@gegham - @Liz  is correct that you cant do this in native Typeform. 

I have done this for a client by working off a ‘two typeform approach’ that you can use with multiple typeforms along with Google Sheets integration to capture and calculate the details

to do this we had someone register on one typeform and then answer a set of questions in the second. we used hidden fields and redirect upon completion to move people through the series of typeforms to calculate 5 distinct ‘duration’ values. 

• capture submission from the registration form into a google sheet - it includes the timestamp of submisison
• when the next form is submitted, you also have the time stamp. 
  • subtract the first timestamp from the second timestamp and you have the length of time it took to complete the question/form. 
  •  

if you want to capture 100 questions and the time on each , that would mean 100 typeforms in this model, BUT it would give you reasonably good values (latency in the networks, etc. have to be taken into consideration …. )
