To get the best results you should try to do the test as honestly as possible and follow the instructions closely. If you are not sure whether you can see an image just select ‘I don’t know’. Do not worry about making mistakes, there is no right or wrong answer. The test will still get you to the correct result.

However, if you feel you have misunderstood the instructions or missed some of the important setup requirements, we recommend you to start over and take the test again or to contact our team who will guide you.
