The only thing we can do is practice and practice. Knowledge is not enough and we need to learn how to apply.
i think that knowledge alone is not enough to pass the f8 paper. it is more of a practical paper and knowing how to apply what is obvious to the scenario the examiner gives. as an f8 full time student (international variant) , my bit of advice is to practice as much past exam questions as possible and not just learn the answers but understand the reason for the answer.
i would like to take part in discussing ans sharing ideas and helping each other along the way.
all the best!!
