✨ COMO USAR O MÉTODO CORNELL ✨
Esse método organiza e otimiza suas anotações em um sistema super prático para estudar durante e após as aulas :
1- Faça uma linha no espaço de meio dedo separando a folha em dois blocos (um maior e outro menor)
2- No bloco maior, você anota o conteúdo da matéria
3- No bloco menor, são os tópicos. Você coloca palavras-chaves, questões e assim destaca o que é essencial e que não pode esquecer
4- Separe uma quantidade mínima de linhas de 5 a 8 para resumir o que aprendeu.
