CFP exam in November

So I used Kaplan college of financial planning and am currently in the Zahn prestudy phase. I am not saying I feel like I know nothing but I feel lost. I did have a shortened period, 6 weeks instead of the recommended 10, to complete the pre study. But I am going through quizzes and failing a majority of them. While I do get 70-80s here and there and I know on some of them I’m tired or rushing but is this normal? I feel like I should be passing these regularly. The in class zahn is coming up. Will that sort out some of this? How did everyone else feel when preparing for this exam?
