If you dreamed that you forgot the material you learned during the exam, then in reality you lack confidence in yourself and your own abilities, which often causes many troubles. If in a dream you successfully pass the exam, then it is possible that in life you are considered a loser, although you do not agree with this. It’s just that everyone has their own path and their own scale of values. A dream in which you use cheat sheets on the exam means that you have decided to get involved in some kind of adventure. If you managed to use the cheat sheet, then in reality everything will turn out well. If the cheat sheet only ruined everything, then think about the justification of the risk.
