Why am I so stupid?

It's almost to the end of the semester. Completed all assignments and tests. But the results were so bad! I even failed my PC1222 end of term test. IS2101 is not any better also. All my marks were just below average. I could only envy my classmates who had above average marks, (and it's all of them).

Life is so depressing! Suddenly, I felt that I have nothing to hope for anymore :(

There's still exams to go, in few weeks time. What more can I do now ?

Why am I so stupid? I wonder, again ~
