TF_101 quiz grading issue

I am having issues with the grading for TF Quiz in module 4. The grader was showing three correct points but giving me 7.0 points. I re-tried the quiz and now it’s giving me a 4. Can you please check and tell me why it’s not telling where it’s going wrong

Hello @sknajmah29 ,

Make sure to stop all the programs from the Shells before correcting the Quiz.
