How to validate results in quiz app in Rails

I want to create a rails app where admin user can create quiz + questions + answers and the user can take the quiz and get results with percentage of results. First part is done Admin can create quiz and questions, I am stuck on how user can take the quiz. Right now I have models:

training.rb

has_many :questions, inverse_of: :training
accepts_nested_attributes_for :questions, reject_if: :all_blank, allow_destroy: true

mount_uploader :image, ImageUploader 

has_many :results
has_many :users

question.rb

belongs_to :training

validates_presence_of :question_name, :presence => true
has_many :results
has_many :answers, inverse_of: :question
accepts_nested_attributes_for :answers, reject_if: :all_blank, allow_destroy: true

answer.rb

enum status: { wrong: 0, 
            wright: 1
              }
belongs_to :question
validates_presence_of :answer_content, :presence => true

result.rb

belongs_to :training
belongs_to :user
belongs_to :question

I was thinking to show the question with 4 answers and on the side to have checkbox, after the user check his answer he can push submit button and I can compare the status of answer(wrong or wright) and then to have the points.
