I feel that I am so stupid.. I believe that I can do it and I study hard but I'm still not satisfy with my results! I think that I can do better than this.. and now I'm doing my revision.. I always forget all the costing formulas and I don't know is it I didn't put effort in it or I am really a forgetful person! Well, maybe myself didn't put effort in my study that's why I still cant get the result that I want.. :( ... Exams is around the corner.. I need to put in more effort.. I believe that I can do it.. I don't wana get disappointed again.. :( ... Hope I can get the result that I want for finals.. T.T...
