Today in my school

Today at school during in lesson english class in my school, my teacher entered the in room to teach learn (your teacher teaches) english but no-one everyone no stopped talking, not even for one minute. He only wrote on the blackboard and expected all the whole class to stay in silence. At the end On end he says: "This is the last time I will what me enter in this that room, I'm disappointed,

but exists five students what me have proud.". "but there exists five students that made me proud" or "but five students who have made me proud exists."

 Then he pointed to at me and more four friends. and four more of my friends.

I was happy for this. (this sentence sounds strange)

This made me happy.

Meeting people

Now that I'm in italki, I've been trying to speak with English speakers. I've studied English at school and by myself, such as grammar and that kind of stuff (no s). But when I try to speak or write, I forget everything like the structure, the words, how who to use verbs, everything.

Well I understand that to improve improving requires hard work,

or

Well I understand that to improve hard work is required,

or

Well I understand that to improve requires hard work,

so I'll continue looking for language partners.

Thanks a lot for your help ;)

I think that your original piece is correct when you are speaking. But in written form, you should follow the corrections I have made in regards to your use of commas.

You are welcome!
