Composition

Hi there [이름]!

Thanks a lot for sending me a message!

Your sentence is correct. I supplied other expression so you can also use it in your future conversation. You did really great. I always appreciate your effort. I hope you\'ll never get tired of doing your homework  and improving your writing skills.

Have a great day! See you on Monday!

I have a question about your correction. 

>>Correct
 *It is what I said during our class: I just got to my office.

>> This is what I said during our class: I just got to my office.
 *It is what you corrected:I just arrived in the office.

>> This is what you corrected:I just arrived in the office.

Is the sentence that I said wrong? Or, is it related to nuance? 

>> Is my sentence wrong? Or it has the same meaning? 
 Please make it clear for me to enhance my skill.
