Timer for the not timed practice section

It would be nice to know how much time I took to finish the questions at the end.

Like, I was practicing the reading section and didn't care about time. After I was done answering all the questions, I wanted to know how much time did I take to finish all 11 questions.

After submitting answers, we see the skill level and can review the answer. It would be even better if we also got the time of completion.

I know I can monitor my time myself but sometime i forget to see at what time I started and don't exactly get the idea of my time management while practicing.

Its just a simple idea which i think would be very helpful especially in reading and writing section.
