TRUE OR FALSE SCORE

I want to create two slides with 5 questions each of true and false, and then also have a results slide after you submit the answers to both of them with the complete score, but I don't seem to find the way to do it. I tried to did it by marking as the correct answers the specific check boxes you have to click, but then the points in the results slide doesn't match with the reality. I'm not sure what to try. I will attach an example.

Someone can help me?
