FSA Exam Retake Advice

I failed GH-301 in Spring and planning to retake in Fall. Have not failed an exam since the first time I took FM but I feel like that was back when I did not understand how much I needed to study to pass an actual exam, so no idea what to do now when I feel like I gave this exam my all. Any advice on how to pick myself back up and re-study for an FSA exam/what to do differently would be greatly appreciated! Searched for the posts on this topic but surprisingly did not find much, only the FSA module retake ones.
