Yes. I'll give you some short sentences to help you understand the tense. Let's suppose some situation. In the morning 6:30, when Cindy have just woken up. Then Cindy's mother will say "일어 났니?(Did you wake up)?" Then Cindy say, "I woke up at 6:30"="나(I) 6시 30분(at half past six/ at six thirty)에 일어났어.(wake up.). And after an hour, Cindy arrive at her school and tell to her friends."I woke up at half past six/at six thirty."="나(I) 오늘(today) 아침(morning) 6시 30분(at half past six/ at six thirty)에 일어났어(woke up)." I hope that helped you. ^_^ 화이팅! This you tube channel below will also help you to improve your Korean language level. http://www.youtube.com/watch?v=KN4mysljHYc

yes.. in korea have tenses.. like present tense, present continuous, past tense, and future tense. but korean is more difficult rather than english

thankyou Amy, yes i mean such as 'past tense', 'future tense', 'simple present tense' or 'present perfect tense', etc. Is korean use that?

Hi Cindy. Are you wondering about how to say "English" in Korean, or grammatical things such as 'past tense', 'present perfect tense'? Since I can't see the intention of your question, adding some more detail or presenting sentences will make it easy for you to get answers from people.
