What should I add to improve my English?- Please check

It's been a while since I  I haven't wrote on here.
How am I doing ? I've got a headache, sore throat, cold etc. I hope , I'm not gonna die , This has that made me miss 4 days of university days but except apart from that, everything goes is well.

How is my Englishdoing? I guess a little bit better: From now on, in addition to my courses, I'm used to participating in "Le café langue", a place where people meet each other and have a possibility to practice English or another language around a table. It's a really a fulfulling experience, you practice and you get to know other people ( students, workers, teachers and so on). It takes place twice a month. Also every I have all Thursday I have 2 hours of extra courses with Erasmus students, taught by an American teacher. I'd like to experience Erasmus next year so it feels like a repetition for me.

That's it, I think I'm done. It's good to write from time to time. Thanks for reading me. :)

Hey. Nicely written. Just a couple of points to help you:

1) In English, everything is good or is well. It can't go well. 

2) Try to avoid using too many commas in your sentences. I think you can join up a lot of the sentences or even start new ones.

The hardest month in university

Good evening everyone !

This month is the hardest for me because I have so many assignments from my lecturer. I have a journalistic assignment, linguistic research and a lot of grammar homework. What makes them very hard is the short deadlines. Honestly, we need more time to finish them. It will/would be better if the lecturer gave a longer deadline, so the students cancould get a better result. Actually, the journalistic and linguistic assigment is for a group. So, it is easier to do.

Not bad! Nice little passage. One point: it will - usually means something that is definitely going to happen. Therefore you should use the conditional tense "It would" to express the idea of something that might happen, or is only possible not certain.

"Flowers for Algernon"- now is my favorite book!

I'm listening to a very interesting audiobook now. This book is " Flowers for Algernon" of by Daniel Kies. At first, I thought that it's a stupid book because the authors voice was very slow and he spoke incorrectly. But then I understood that the main hero of this book is an unhealthy young man.
His brains were incompleted. ??? Not sure what you mean here. 
One day group of scientific scientists decided to operate on him to make him cleverer.
So the book is about his life after this operation.
Very deep and impressive book. It makes us to think about other unhealthy people, about their lives and their viewing of world.

Not bad! Just watch out for those prepositions like to, by & on!

Disappointment(

Today was a very sad day. France winsbeat Ukraine 3:0 and will go to Brazil...We were very close to the target (Ukraine won the first match 2:0) but this World Cup in 2014 will again take place without Ukraine. It's really a big disappointment. Next chance will be only in 4 years((
I want just to thank the National Team of Ukraine for their eagerness and congratulate France with for their victory.

Nicely written.

Just to note: When using 'will' it should be followed by a verb. 

P.S

I'm sorry Ukraine didn't make it tonight!
