I detailed my study and exam experience on the sub a few days ago , but I can say that Lehmann 175 is difficult and was trickier than the exam . I agree with your thoughts on the Rita quizzes , but I think your scores are pretty good . I am not familiar with PMTraining . Search the sub for reported scores . I paid for the PM Exam Simulator , and I think it did a decent job of preparing me for the exam . PM Exam Simulator has some free examsexamsimulator . com , but I never took them since I used the paid version and I don ' t know how they compare they could be the same , don ' t know . I ' d say your scores are decent enough where you don ' t need to spend more money on practice exams . That said , don ' t let your guard down . Continue identifying and studying your knowledge gap . And continue taking practice exams . Good luck !
