Punctuation Marks and Etc. of the English Language

GolamMostafa:
As a non-native, I need to re-write the above sentence as follows just to get pass of the English as a second language.

If you don't have some kind of rules, things can be a bit difficult to follow; and, it becomes harder to communicate.

....

I see what you mean you are actually having to be more dilligent than the native speaker.

GolamMostafa:
....
I must honor the rules of combining together the dependent clause, independent clause and transitional adverb through correct use of the punctuation marks.

I only speak one language and I don't have a formal understanding of it's grammatical rules. I am sure that is a bad thing. I suppose though as a non-native a lot depends on what level of study you are undertaking. If you are studying at University level being tested on a formal understanding of the rules probably makes sense.
