1. What score did you get?
I got 22.
2. What is your score?
It is 22.
3. How much score did you get?
I got 22.
4. How many scores did you get?
I got 22.
(Are all grammatical and the same?)
5. Add up all the scores, and then you can get the total score. What is your total score? It is 17. Really? That means your are happy?
(Are the pasage correct?)
1 and 2 are fine, and they mean the same thing; 3 and 4 are not, but wouldn't mean the same thing even if they were corrected.
5 is correct.
5 is fine except for the last line "That means your are happy?". 'That means you're happy' is a much better sentence.
Jordan is right. It should be "you're" or "you are" not "your."
1. "What score did you get?" - This question is grammatically correct and can be answered by saying "I got 22."
2. "What is your score?" - This question is also grammatically correct and can be answered by saying "It is 22."
3. "How much score did you get?" - This question is grammatically correct, although it would be more commonly phrased as "What score did you get?" or "How many points did you get?" The answer would still be "I got 22."
4. "How many scores did you get?" - This question is grammatically correct, but it would be more common to ask "How many points did you score?" or "What was your score?" The answer would still be "I got 22."
Regarding your fifth question, the passage is slightly incorrect. Instead of saying "Add up all the scores, and then you can get the total score," it should be "Add up all the scores to get the total score." The question "What is your total score? It is 17" is grammatically correct, but it seems contradictory since you mention a total score of 17 and then ask if the person is happy.
