I will meet my old friends today in Singapore.

My best friend told me that one of my Chinese high school classmates has come to Singapore. He arrived several days ago before. And he My friend gave me his contact details. I texted my classmate this morning and we chatted for a while. We never have not seen each other since we graduated from high school. It's almost been 10 years!

And he works in National University of Singapore too!

1. And Like me, he also works in the National University of Singapore too! - use this sentence if you mean he also works in the same place as you.

2. And He also works in the National University of Singapore too! - use this sentence if you just want to say that your friend works in the National University of Singapore.

I will meet him at noon and have lunch with him. What a day!

Great work, only some minor errors. Well done.
