Its pretty good. Two things
1. after submitting an answer the page reloads at the top instead of 
where I was looking at last, so I have to scroll down to see the result 
answer and the next question. Maybe this is a chrome thing.

2. The `time-to-school' question tells me to input the expected answer 
in the second box but this text appears before there is even a second 
box. Initially I was confused and then I understood what was happening 
after I submitted something in the first box. I suggest just displaying 
the text about the expected result after the user presses the submit 
button for the first box.
