Was my alarm clock?

On Monday night, I put new battery and I promised myself I will wake up at 5:00 a.m. and I will study for tomorrow reading test. My roommates are saying same words about tomorrow test and wake up at 5:00 a.m. It looks like impossible, but I did it. Only 30 seconds.

Today daybreak at 5:00 a.m., someone alarm clock was rang very loud but fortunately, dorm parents ware not coming to our room because we closed the door already. I heard that rang loudly but nobody turn off an alarm clock. If they asked, why didn’t you turn off an alarm clock I will say because it is not mine? Or because it is too far from my bed and I don’t want to go down to the floor, turn off the alarm clock, climb and go back to my bed. Was it too far from me?

I thought an alarm clock rang already 2 minutes and somebody turns off an alarm clock. Finally, I can sleep comfortably and peaceful.
As a result, I didn’t finish my study for test.
