A question regarding grading of multiple choice questions

Hi. Long time user. Big fan of the site.

Can you explain the grading system when it comes to multiple choice questions on Khan Academy? In most cases, I need to select correct number of options and answers are either right or wrong. Displayed in green for correct and red for incorrect. Pretty straightforward stuff.

However, what is the meaning of answer being marked grey with green text "correct"? It's sending me mixed signals (no pun intended). I should also note that I've only had 1-3 questions like this. They seem quite rare.

Is it supposed to signal that the answer is correct; something which I should have also selected?
• Usually I can't even submit my answer until I've selected correct number of responses. I get a notice.
• If I should have selected it, how come the answer is the exact opposite to the comment below it?

Option:
"When an antenna is transmitting (sending) a signal, incoming EM waves cause electrons in the antenna to move."
Comment below it:
"When an antenna is receiving a signal, incoming EM waves cause electrons in the antenna to move."

Hi there!

Multiple selection questions (where you have to pick multiple correct answers) behave as follows:
- Answers that you correctly selected will be shown in green, with the text "Correct (Selected)". Option A demonstrates this in the image below.
- Answers that should have been selected will be shown in green, with the text "Correct". Option B demonstrates this in the image below.
- Incorrect answers that were selected will be shown in red, with the text "Incorrect (Selected)".
- For some questions where you are required to select a certain number of answers (i.e. Select the 2 statements that are true) will force you to select exactly 2 options before submitting. More general questions (such as "Select all statements that are true") will allow you to select any number of answers.
- The grading for these questions, in terms of your overall exercise/quiz/unit test score, is all or nothing. You must select all of the correct options, and nothing else, in order for the entire question to be marked as correct. In other words, there's no partial credit for these questions.
I hope this helps! Please let me know if you have any further questions!
