exhaust!!!

What i want to say i never done to my job and work.We are so hardly to juggle between the job and school assignment simultaneously. it is nearly exhaust all my energy when i back to the home. how can a student constant working in day and night, haiz...i am tired to death...almost. sometime, i do not understand why i should go to all this effort....working time is reduce my study time. damn it! i just got a poor grade on my test!macro 74mark. i failed answer the simple question... and the accounting....i am looking forward to get a good result...but..it's all gone...what i thinking?just calculate the depreciation value it a basic knowledge from secondary school...it should not be happen but it all happened. fine,i really need to carefully think about this,seriously!
