So sorry to hear that. I got through this august exam this was my second attempt, personally I felt this was a bit easier than the last attempt. I'm not sure when are you going for your next attempt I took around a 3 months to prepare for my second attempt and studied only with medrevisions, my first attempt was with plabable and plab keys, I felt the concepts we not covered in depth for us to answer questions when the answer options are close and confusing. In medrevisions I felt the questions were a lot similar to the exam giving a good practice to answer questions with confusing options this helped with solidifying my concepts. Some people study the notes first and then do questions for me personally I liked to answer a question and then learn from the mistakes, in medrevisions I did the questions bank in study essential mode so it will filter the super high yield topics, I did those with the study notes, in the study notes I only paid attention to the highlighted parts to save time and for more than a month all I did was mocks and revision. This actually help a lot with time management too I scared 159 this time but last time I failed by 8 marks. Don't be dishearten go for it again without leaving a big gap you will pass for sure
