>>13522123At my first year at uni, i realized my math knowledge was FULL of holes, i could not make the simplest of exercises (went to public school entire life, brazil)
So i stopped going to classes and started spending all morning in the library, i started to study math FROM ZERO, THE BASICS, up untill uni level.
It felt retarded at first, "learning" things i took for granted and was confident i knew.
It was the best decision o my life, when next semester started i crushed anything that had math in it.
It was hard, tons of exercises and time, but it was worth it a lot.
