pretty simple just dont give up is best for a start, if you get complacent you will expect the worst on dec 16th. Start studying dont worry about the outside sides like scaling down ranks etc.
mate dont give up its not the end until its actually over, so keep trying and dont slack off and work your hardest til your last exam. Best of luck mate and if that doesnt work, there are several pathways, so its not end of the world for you just yet mate :)
