Hello, 

I have a macbook and I have Bluetooth keyboard, mouse and also, a numeric pad to use for inputting the numbers in the calculator for the calculations. Are these allowed?

Also, I connect my laptop to a big screen, is it allowed, if I disable the double screen feature? (as I understand I need to keep the laptop open as the camera is there).

Last but not least, I will be in a house where there may be some noise (I have dogs that occasionally might bark, for example). Can I wear earplugs to minimize the noise? 

Thanks for answering.
