Hi Gabriele Yes they tell you how many options can you select. If you select more than the correct options it also tells you that you have selected more than the correct answers. But if you select less then it would not tell you. Secondly if you asking whether you can take a paper for rough work the you can but that will be provided by the test center and you will have to return the same to the test center. They may also provide you with a pad and a marker.
