1. It's 8 minutes. But beware: you will need to have your fingerprint scanned every time you come or go in the room, so discounting the time you lose with this it will be only about 5 mins.

2. No, you do not. The session will start immediately.

3. No, you do not. You have a convenient search function (by country, state, name etc. I believe) at the end for school reports.

4. I do not think you can. However, if you run out of space, you should raise your hand and ask the proctor for a clean one. He will take the one you've just finished writing on, so that at any given time there's only one pad with you in the room.

Thanks a lot for your response.5 min is too less as a break.
