Actually,you can take a real test on line and that's almost the same.But u know,you must be consentrate on the test when you start , cause maybe you are the first one taking test and the other people will entering room continously.So, when you doing listening,probably other guys doing speaking,pretty funny.The test room really like a market sometimes.
I think you only allow to takeing pencils and ID, and water and snake you can put them in other room. And,after listening part you will have 10mins to have a break.The computer will tell you anything you want through the test. You cannot choose the order.ToEFL still formal.
sorry, is snack not snake.
