The most competitive undergraduate programs are Medicine with a 0.5% acceptance rate, Architecture and Urbanism with 0.6%, and Communication with 2%. Such high competitivity leads many students to take preparatory courses during or after the last regular high school year called cursinhos in Portuguese, generally privately offered or managed by some association or organization. Many private cursinhos have special classes focused on highly competitive programs like medicine, making them very expensive. It is common to find students admitted in Medicine, Engineering and other programs after several years of preparatory courses.
