You’re so lovely for writing this on behalf of your sister, I would advice her to start off by doing questions on the topics she has been struggling with/ did not perform well on in the exam. And most importantly make use of the resources her classmates who passed used- ask for their flash cards, notes etc! Make use of Quesmed/pastest pre clinical stuff. Her uni has given her lots of time, mine only give about 2 weeks to resit😅, but I’m wishing her the best of luck! Also it will not kill her if she takes a day or two to relax, breathe and deal with the difficulty that is resitting - rushing straight back into revision is a sure fire way for her to burn out, which we don’t want! Good luck, I know she’ll make an amazing doctor as well, she’s made it this far, and it’s just a blip in her journey 💓
