i failed my P&C insurance exam and im so confused.

i recently came on here earlier with a different question, but i did fail. im so confused because i was using the insurance exam queen and a practice test site and id pass with a 80-96%. however, the questions were different, and some of the questions ive never seen before.
i took the sc exam, is there anything that i can do to study and get the hang of? any recommendations of books or sights are fine. i just feel so shitty about it because i worked my ass off.
(for those wondering, the passing grade is 70%. i got a 50%.)
