How was I supposed to know what a singular matrix is? Sigh, 4 marks down the drain all because of an obscure sentence on line 7 in page 5 of my textbook that escaped me.
'If |M| = 0, we say that M is singular'
Otherwise, the only thing that could bring me down is my carelessness. Tomorrow is A Maths Paper 2. Been doing Prelim compilations since noon. That's a measly 2 hours and 40 minutes spent.
On a side note, I hope the renovations, drilling, painting destroying will be done soon. It has been extremely distracting since it started two weeks before my exams. In fact, studying in the PUBLIC LIBRARY, that's right the one filled with noisy neighborhood school students, was more productive.
