F3 OT

Hi

I recently sat the F3 exam online for a second time after failing the first time and the exam this time was really difficult and failed again. I had studied solidly for 1 month with a mix of in depth understanding of the theory and practice questions. The exam had questions that were briefly touched in the text study or no direct example in the practice tests.
Examples include complex exchange rate and libor questions which completely threw me and as most of these complex calculation questions were in the first section resulting in the rest of the paper being a disaster and a lower score than my first attempt.
I have found the Opentuition lectures by Chris really valuable and helped my understanding but I am not sure why I struggled so badly in the latest exam.
Any advice would be really welcome on what I need to do to pass this F3 OT as it’s the final strategic OT paper.

Thank you
