Every Tuesday, always at 7 pm, I give live classes to teach you everything I know about BIOLOGY and APPROVAL for ENEM and other entrance exams. However, I can tell you that few classes will be available here on the channel, as all recordings will be made available exclusively to my Biostudy students.
