Saw junior made me missed the past

Currently at the college CITC...
the girl beside me is doing her tutorial...

seeing her doing the matrix made me missed the time when i was doing it when in Diploma lvl...

then i looked up of her tutorial paper and i saw

but the only thing that i liked is matrix...
always found myself enjoy doing that tutorial..
