Hello everyone again.
I wanted to write a formal letter about the ways of improving a site (not this site). But I'm not sure whether my letter is correct or not, because I have problems with any letters. This is my text:
Hello. I suppose that the levels here are not similar to the levels of English courses. For example, I have an advanced level here. But my really level is upper-intermediate. I think this system must be remade.
As well, a content for advanced look like the content for intermediate level.
I hope this system will be improved as soon as possible.
If I have mistakes, please, correct them. I want to be good in letter writing.
Thanks in advance.
