It is helful due to the huge amount of questions it contains, but not as much helpful as one first could think because of its excessively quantitative nature. You may find yourself losing much time performing pointless calculations. CFAI questions are much more conceptual.
Still, if the cost doesn’t hurt you and you save time also for EOCQ, I’d say go for it. Just skip the questions regarding calculation of variances and all that stuff.
