do you know how it feel when we have tried our best, but in the end, we dont get what we want??about 2 or three weeks before, i got a differential equation's test..i worked very hard so that i can score in this test..and after the test, i felt confident and i really think that i can get high mark..unluckily i just got 18 over 25..so sad..huhu..my target to get an A for this subject seems hazy..just like malaysia's weather..it's all hazy and unclear..huhu..nevermind..i'll try my best in the final..
anyway, have you ever tried the number puzzle, sudoku?i have..and i stuck on it rite now...for now, that's the way i filling my leasure time..this easy looking puzzle actually is not very easy..for a beginner, i always take 1 hour to complete a puzzle..i really love this puzzle since it challenge my mind and it trains me to focus and stay alert..try it and you'll find so much fun..this puzzle consists of 9x9 squares..and you have to fill the squares with number from 1 to 9 so that every row and column have number from 1 to 9,and for every 3x3 square too..ok, till then..wanna play a sudoku before study..
