Dear all my lovely friends,

Now, here is like a battle field between difficult stubborn books and Korean University students [in Korea] actually you don’t have to put the Korea here as it is understandable that the students are Koreans, it will just make it redundant . It is very tough seriously. From last week to 2 weeks later,because there will be final examinations in most Korean Universities.
Perhaps it’s more concise this way [It is very tough for these last 2 weeks because it is going to be the final examination in most Korean Universities]
Some of my friends [have studied ] Present perfect tense   all night in library and some people are [getting] becoming zombies, including me. As you know, many students commonly look for energy-drinks like Red bulls. [It is not a commercial comment] There is a better way of saying it (this does not imply endorsement) to get a power to study in exam time. We are [addicted] to [those do not use ‘that’ since you are using plural form, which in this case are the’ drinks’] kind of drinks and Academic words.

I always want to get a super-good grade in every [class A noun and the words that modify that noun must agree in number ‘every class].] I have taken. However, the problem is I don't want to study now. So, (always put a comma when using transition words like this) that is [ironic] this should be adjective as you are referring to the situation       and this situation makes me totally exhausted. I know I have to do something to get better. If I don't study, I never can [can never] have a real smile after finishing the finals. It is true. So, I know the reason why I study. "I cannot always do what I like. I am not a child." [Right. I can do. I just say to myself. "See you my every stuff which makes me enjoy in my head." ] You lost me here

I've got to go back to study. Hoping to see you guys if I survive during the final period. [ Hope to see you guys if I survive during the final period]

Stay warm, everyone.

I hope this helps and good luck with your finals! :)
