What is wrong with you when you have passed all mandatory calculus courses (with shitty grades), and still can't remember the multiplication tables, and can't count out change sometimes.

Also, 2 weeks after the exam, most of the things i had "learnt", or re-learnt from high school were already gone.

How do i prevent this from happening?
I rarely use math for anything, except the before mentioned things that also i fail at.

What do? Im frustrated with this.
I thought the point of going to college was being forced to learn boring things that you otherwise wouldn't.

I weep for humanity..

Might as well...
