Baricentro

Baricentro is a centralized location with an ever-expanding and free collection of questions. The great advantage of the platform is that it centralizes questions from entrance exams and textbooks in mathematics, physics and chemistry. Do you know when a book only has the template (or sometimes not even that) and you don't know how to get out of the question? It would be much faster if this problem didn't exist. Because that is the mission of the site.
