After purchasing your test credit(s) you will need to generate licence code(s) in order to use your tests.

The licence code for a test is a 16 digit string containing letters and numbers.  It acts as the unique reference for your test and will be printed on your certificate upon completion.

Please log into your account at and select "2. Generate licence code(s)".  To generate a single license code, put a "1" in the textbox before clicking the button, "Generate".

Your licence code will be generated immediately. When you are ready, click "Start test" to begin the test - if the test is not finished after 36 hours it will expire and cannot be used again.
