I don't know what kind of exam it's you failed but if it's something book reading you need to do to clear it just a advice read a full chapter understand it then write it on a paper and make a file and that would be your new book for chapter and when you make it yourself you know what important and what not and most of all it be short and precise and be much easier then reading two pages to understand each topic but if it's some kind of practical exam try to put practice in your daily life activities or something so come to you naturally
author I understand you literally a year ago I failed an exam and I was very. (ノ-_-)ノ~┻━┻about sending everything to the trash so I understand the feeling I also think you can do better the next exam remember that you have failed now It means that you can only continue learning and improve your spirits for the next exam.
