I actually passed my 3 Applied Linear Algebra courses with flying colors by just remembering all these results because the lecturer never tried to explaine what's happening behind the scene. So after almost 20 years I'm still here trying to figure out what's what. I shoulda gone to MIT.####[['MIT', 'Other', 'POS'], ['Applied Linear Algebra courses', 'Course_General_Feedback', 'NEG']]
