Free PI BA should be restricted and not freely available to all

There are a lot of cases when the candidate go on to the global website and try the PI BA before doing it via the link shared by the company. We have seen that when done quickly one after another the results varies a lot. The PI methodology states that the first response for self is the best one. But by providing free trail BAs we are negating the capability of PI to capture the most natural response of the candidates. Request to limit this feature to a stage where its established that the person doing free assessment is not a candidate but someone evaluating the system for their organziation.
