Sad day......

This should be posted yesterday but due to some circumstances, I delayed my blog.

I sat for my chemistry quiz yesterday. It was a tough one. I had been scoring full marks for the past two quiz and it was really a bit pressure when I sat for my quiz the day before. The formula I expressed very nicely and I was certain with which Rydberg constant I should have filled in. Yet, I was like losing my consiousness; I filled in the constant with Planck's constant. At that particular moment when I knew my 'glaring' mistake, I felt like committing suicide! How could I make such a careless mistake. That leads my chesmitry quiz to a complete failure, I suppose.
