WeyFen came look for me this noon to compare our answer of all the Calculus III past year paper. Both of us were so careless for making so much mistakes in some calculations. I often confuse between differentiation and integration after doing so many questions on differentiation and integration. Exponential is also something headache for me. Sigh... Just hope that I won't be so careless and confused during the exam on this Friday. Worked on Operational Research for the whole day. Operational Research is not something easy to do. The steps are actually known, but the calculation is just too troublesome. It is easy, but it is even easier to make mistakes. And when these mistakes occur, everything is gone...
No time to grumble about all these, I should get back to my work.
