puts "Alunos\n\n"

alunos = [["Daniel: ", "Nota: 10\n\n"],["Abima: ", "Nota: 10\n\n"], ["Wilame: ", "Nota: 10\n\n"],["Felipe: ","Nota: 10\n\n"]]

puts alunos

I wonder if it is possible to add a new student with a new note as a new array in the array above, so that the parameters would have to be typed in the terminal.

Just use the push() method than the type array already has:

puts "Alunos\n\n"
alunos = [["Daniel: ", "Nota: 10\n\n"],["Abima: ", "Nota: 10\n\n"], ["Wilame: ", "Nota: 10\n\n"],["Felipe: ","Nota: 10\n\n"]]
alunos.push(["João: ", "Nota: 8\n\n"])
puts alunos
