It is often that when I study or start a course, I put my 100% effort on it at the start of the studying I like to give my all into it to start with good grades, but slowly when we end the semester I reach my all and seem to be tired, sometimes I use all the effort in the start and don't give a fuck at the end. This system usually works when there is a lot of evaluations so the first good grades make me pass even if i slack at the end. This time I just have one final exam and after a month studying I can't anymore Im tired
