Thanks for reply.
But Question 1 is about personal history, like we declare employment, educational activity, unemployment... When I was a student in France from 2011 to 2014, and I travelled a lot around Europe as well as home country, do I have to traveling activities while being student in personal history?
If your traveling history to those places include just one or two days. You don't need to include it. But if you are staying there for months. You will need to include it.
All I'm saying is. Try not to have any empty timeline on your form. Every month and days of the year must be listed. If not. You might not be able to validate your form
