I think there's faults in Frequency distribution table (Cumulative frequency)

Good to hear from you. Could you elaborate, please as we need to make the appropriate changes if that is the case.
Arranging the frequency from top to least then you create cumulative frequency like that I learn in the lesson but in the exam you don't do the same.
SPOILER: one of the answers on the practice exams is given here, so don't read it if you want to try yourself
I think so too, if you add all the numbers in the cumulative frequency column, you get 97% --> meaning that the row with the missing frequency should equal to the remain 3%. However, the official solution to question 5 = 4%, which I also think is a mistake...
