Think that a question includes 10 elements, in other words 5 pairs that you need to figure out. Once you are wrong with your first attempt -assume that you're asked to match countries and cities and say you paired USA and Paris-, should you wait until you finished with all 5 pairs and then submit?
Or can you have an immediate bounce back? So, you won't need to submit anything! And most importantly, the screen would be more interactive
Is there anyone who experienced this before?
