Mid-term Test.

My mid-term test is coming (or 'soon'). Since coffee makes me super dizzy, I tried to drink energy drinks instead. I heard that to drink drinking energy drinks often or everyday is not good for your health. So I might have to start drinking coffee again. I can't wait to end my studies (in 3 years and a half years, which is still a long way to go) but my friends said working is far more harder. So I wonder what I really wanted (to do). Whether (I want) to end my studies as soon as possible or to work as soon as possible. But seriously, I am not a fan of examinations. I wish I could go to class without worrying about marks and such. Anyway, ganbatte! I can do it!

Good work, just a few small errors and a few corrections were simply added to make your writing sound more idiomatic. :)

Mid-term Test.

My mid-term test is coming. Since coffee makes me super dizzy, I tried to drink energy drinks instead. I heard that to drink ("drinking" would be more standard) energy drinks often or everyday is not good for your health. So I might have to drink coffee again. (So I might have to go back to drinking coffee.) I can't wait to end my studies (in 3 years and a half which is still a long way to go), but my friends said working is far more harder. So I wonder what I really wanted. (- or :) whether to end my studies as soon as possible or to work as soon as possible. But seriously, I am not a fan of examinations ("exams" or "tests" is more common). I wish I can could go to class without worrying about marks (grades) and such. Anyway, ganbatte ??! I can do it!
