ok!!!
^^
nice to meet u.
im just come back from korea.
very beatiful country.
i want to go there again.
^O^

no worries! as long as you reply back(:
my friend introduced me into big bang.
do you like them?

hey! ^^
not much. im just sitting here in the school library
while my friend is watching 우리 결혼했어요 haha
and you?

oh.. aww, that sucks~ >_<
but im sure you'll do better next time!! :)
so don't feel bad~

and yes, i do know MC Sniper! lol
i love his music~ xD
anyway, wow.. really?? :O so lucky~
what was he doing there?
performing? visiting? lol
and yes, i agree. very cool ^^

okay, corrections.​.

"today i saw my statistics score of midterm"​
not bad.. but it sounds awkward lol
"today i saw my statistics midterm grade" would be better, i think lol

"i was disappointed​ at my score so that score make feel bad" -->
"i was disappointed​ with my score"
being disappointed​ with your score implies that you felt bad
so i don't think you have to add that last part lol
but if you want to add it in..
"i was disappointed​ with my score; it made me feel bad"

"i really like that" lol im assuming you're saying you like
MC Sniper, right? rather than using "that"​, it would be better
to use "him"​ because MC Sniper is a person lol

"1 months ago i saw him in Pukyung National University where there is it near by my home"
it should be..
"1 month ago i saw him at Pukyung National University, which is near my home"
1 month is singular cuz it's only 1 month~

"her song is very cool" --> you're talking about MC Sniper, right?
lol the only problem with this one is that MC Sniper is a guy
so you would use "his"​ rather than "her"​ lol

lol sorry if it seems like i fixed a lot or whatever ._.
it's just little problems for most of them
so i end up having to put all :x lol but yeah, anyway..
have a good day~ ^^

hi
^^

hey! lol no problem :P
and it's all good.. my response is late as well! sorry~ >_<
oh, really? a water clock? interesting.​ lol
anyway, it's all good.. i've been busy with school too anyway xP lol

school is pretty tiring because i have to wake up so early! :(
but other than that, i guess it's okay lol
i still get to see my friends and hang out with them so yeah haha
it's not too bad.. what about you? ^^

and okay, well.. hm..
"sorry for replying your message so late"
it's just a tiny mistake but.. it should be
"sorry for responding to your message so late"
or if you want to use replying.. then i guess it could also be
"sorry for replying so late"

"i had had many reports and group homework that our team members have to make a water clock"
this is also correct for the most part.. but you don't need
to use the word "had"​ twice lol
and the second part of it.. "...rep​orts and group homework for my team to make a water clock" this would be fine

and im not really sure what you meant when you said
you had to give air to the refrigerator​.. ^^;; sorry

anyway, your english is really good!
you don't really make any big mistakes lol
it's usually small mistakes~ lol
yay, good job! ^_^

hey there....how​ is your week going?

me...okay...​.just relaxing with some friends at Starbucks and sharing some smokes....

Hello :]
60 Members in your club? That is a lot.

That's nice of your senior friend to have given you advise. ^^
Haha, have you introduced a girl to your friend yet?

My day has been okay so far. It was raining yesterday, so I liked it a lot.

"so today is holiday"​ - So today is a holiday
"And at there, I met my senior and friend"​ - And I met my senior and friend there"
"So he advised me for me about useful things."​ - "So he gave me some useful advice"​
"so he asked a favor of me  that i introduce to him my girl fellows"​ - "So he asked me for a favor that I introduced my girls friends to him

Take cares :)

Hey
I'm good, just a bit tired right now ^^

It seems like you had a very fun time playing tennis ^^
I haven't play that in a long time.

How many siblings do you have in your family?

"that have a good taste" -> It was very delicous
"but i lose in the games" -> But I lost in the games
"after playing league game we drunk and told too much" -> After playing the league game, we got drunk and said a lot."

annyong!
how are you today?

Hello. It's okay that you replied late. Now and days people are busy. ^^'
Everything is fine, just a lot of homework to be done each day.

My favorite sport? I don't really have a favorite sport because I don't play very well. Haha.

From what you written, there's no mistakes to me. :]
