나의 하루 (My Day?)

안녕하세요!

오늘은 수업이많아요. 아홉 시에 국제관계학 수업이 있었어요. 너무 지루했어요! 오후에 집에 갈꺼에요. 

mostly I agree with first correction. but with the last sentence I have different opinion.
 오후에 집에 갈꺼에요
if you wrote that sentence at school before going back to the home you can you present tence or future tence. 오후에 집에 가요 or 오후에 집에 갈꺼에요.
if you wrote after coming back to home, you should use past tense. but in this case we don't say 갔어요. you are already at home so you should say 'came back' which is 왔어요. 

 so 오후에 집에 왔어요. 


My teacher said 국제관계학 means international relations, is that correct? yeap~
