Then run the following script by executing the following command from the
rails console:
load "test-student.rb"

s1 = Student.new
s1.first_name = "Chloe"
s1.major = "Biology"
s1.year = 3
s1.gpa = 3.79
s1.save

s2 = Student.new
s2.first_name = "Maxwell"
s2.major = "English"
s2.year = 2
s2.gpa = 3.62
s2.save

print s2.count, "\n"
