Bear with me here. First ever exam. 1. Why 10 working days? (especially since the alternative is just 2 days) 2. How many hours per day? 3. It's online. So why did I have to specify an exam centre? (of which there are none in my country) Thanks.
for your point 3, at least it seems not required to choose exam center in the process of exam registering for the online version. for your point 1 & 2, due to it's online version, my understanding is that 10 working days instead of 2 on-site day ease time schedule arrangement by yourself, considering the students may live in different time zone. There is no hard required on time spend for each day. By the way, I just sit the online exam Nov 11-22. For your reference.
