There are a little difference between the beta and live exam, as for the number of questions in the
test, and the time allowed.
In beta, you will go through around 160-170 questions, with 4-5 hours. In live exam, you will only get a portion of them with 1.5-2.5 hours.
But when you receive your score report, it will not show how you did with all 160+ questions, it will only show you the number of questions that are as same as the live exam. Thus, you have no way to know the actual performance of your beta exam. The certificate will not mention whether it is a beta or not.
