Should the browser closes for any reason, and you lose the
connection while you are solving an exercise, you have to know that the
problem data are kept so you can continue with the solution
later, as long as the problem time has not expired.
If you leave some question unanswered after clicking on correction,
e-status will allow you to answer it and to complete the exercise
(clicking again on correction).
Anyway, if you want to end the exercise without answering some
question, click on accept mark.
Some questions at given problems allow for several chances to
answer them. In that case, whenever you enter a wrong answer, this
value is returned and you are asked to enter a new response in a white
box. Then, click on correction,
or choose accept
if you are not able to give an alternative answer.
