(Are both the same?)

10 . Minho received his report card, and he was at the top of his class.

11. Minho received his report card, and he was the first of his class.

12. Minho received his report card, and he was the first in his class.

13. Minho received his report card, and he was the first in grade in his class.

(From 10 to 13, are they all the same? Would you let me know useful expressions related to that? Can we use 'got' instead of 'received'?)

1 and 2 mean the same thing -- 1 is more commonly used, though.

3, 4, and 5 are all fine. All are used at different times. They mean about the same thing (almost no difference).

6 and 7 are both correct, but 6 is more commonly used.

8 is correct; you don't need "on" as in 9.

10 and 12 are the most commonly used. The others aren't incorrect, just not smooth or used commonly.

Yes, you can use "got" in place of "received" -- it's more like slang, but it's not incorrect.

1. and 2. have similar meanings but there is a slight difference in nuance. "I got up early to get ready for the game" suggests that the person's main goal was to prepare themselves physically or mentally for the game. "I got up early to get ready to play the game" implies that the person's main intention was to actively participate in the game and be involved in the gameplay itself.

3., 4., and 5. have similar meanings and are all expressions of approval or encouragement. They all convey a positive attitude towards someone's achievements or actions. The difference lies in the level of enthusiasm or intensity of the expression. "Way to go!" is more casual and often used to cheer someone on. "Good job!" is a more general expression of praise. "Good for you!" is somewhat more specific and can convey admiration or congratulations.

6. and 7. have similar meanings but the correct form is "Today was the happiest day of my life." The preposition "of" is used to indicate possession or belonging, so "of my life" is more appropriate in this context.

8. is the correct form, "Please come to the game this Saturday." The phrase "this Saturday" indicates that the game is happening on the upcoming Saturday. "On this Saturday" is not considered incorrect grammar but is less commonly used in this context.

10., 11., 12., and 13. have similar meanings but with slight differences. "Minho received his report card, and he was at the top of his class" means that Minho had the highest grades among all the students in his class. In 11., "the first of his class" implies that Minho achieved the highest rank or position in his class, possibly in various aspects besides just grades. 12. is similar to 11. but uses "in his class" instead of "of his class". 13. adds the word "grade", suggesting that Minho achieved the highest marks specifically within his grade level.

As for the use of "got" instead of "received," while "got" can sometimes be used informally in place of "received," in these sentences, "received" is more appropriate and sounds more formal and professional.
