can u please check my grammers?

I would like to speech about my journey.Guam was the most impressisve place I ever had been, when i was in middle school.I only had a trip abroad, which was Guam.
It was long time ago, but I can still remember the trip was very exciting.I was very fluttering, and happy, because it was my first time to air trip.I learned lots of experinces, and found different things.I remember one of my experience in Guam was scuba diving. wearing swimming goggles, bring fish foods in the water(sea), watching fishes under the water. I really enjoyed it.I also ride on banana boats, went to aboroginal town, watched their tradition dance, people pluck the coconuts on the tree and learned myth of the Guam..

I was in Guam only for five days, but I had valuable experience. I learned different cultures and took lots of pictures for rememberance.

Ive seen some cerebrities on my way back to korea.

can you please check my grammers? thank you
