So i'amI've been studying cChinese for 4 weeks already, and iI find it very fun and entertaining. I am learning it on cCoursera and the lessons seems to be really effortless and comfortablehelpful, although we are not supposed to learn cChinese characters oin this course. Hope ifully I will write small texts in cChinese as soon as possible!

"Effortless and comfortable" don't really make sense to me in this context.

"I am" is often written/said as "I'm".

You have to capitalize proper nouns (ex. "Chinese") as well as "I" when you use it to mean yourself.

"I will" is often written/said as "I'll".

"We are" is often written/said as "we're".

When iI started the course i, I would never have thought that iI would enjoy it and would keep doing it for 4 weeks already.

You're talking about your past perspective here, so "already" doesn't make sense.

And also, it was nice to know that we have similar sounds in aAzerbaijani(, which is my native language), and that is why the pronunciation of the letters was not too difficult for me.

"Was not" is often written/said as "wasn't".

"That is" is often written/said as "that's".
