About italki teachers

I'm very dissapoint disappointed about the italki teachers because when you schedule the session they give you hope by agree agreeing to the request. After that they send you a msg saying they have another schedule or another excuses.
I think its better before agree agreeing they have to check their your time and everything before agree agreeing to the student. This causes a problem sometimes you fill like giving up sometimes causes a problem, so you feel like giving up. All the time same excuses same problem.
I'm requeasting requesting all the teachers to be carefull careful with their calenda's calendar's session before accept the session.

June is a time for graduation. I went to Shenyang Teacher’s university. Every students sold their stuffs in on campus that she used during school cause because they can’t take everything to home or to work. I spent one Yuan on a brush from a girl, and one Yuan on a bottle of ink from another girl. That is very cheap. You know, one Yuan only can buy an some ice cream. I studied Chinese calligraphy when I learned was in high school. I want to practic practice it. But I didn’t buy paper for Chinese calligraphy cause because I did could not find where I can could buy it. So I only write wrote it on A4 ordinary paper. 

I write wrote some words that is mean“yesterday is history, tomorrow is mystery, but today is a gift. But I felt that is was not so good.

P.S. The reason for the first comma I highlighted was because you are saying two complete thoughts in one sentence.

World of Warcraft, Counter-Strike, Grand Theft Auto and others are the games that literally blow our minds far away. They elevate computer graphics to the next level. When we play, we are teleported to an entire new world. But do these games impact us positively or negatively?
Your grandma may think that there is no positive side at all, but she is wrong. The University of Medicine in Chepelare proved that gamers have bigger imaginations and more developed brains than ordinary people. Another benefit is the feeling of pleasure when you win the game or go to the next level. It really brings you fulfillment. Playing racing games is also an advantage. It helps your reactions become faster on the road and this can avoid car accidents.
Nevertheless, there are disadvantages too. Sometimes it is easier to starve the monitor(not sure what you meant here) and live the world in the game instead of engaging with friends. This really destroys your social life. Harming your eyes and getting fat is also a drawback. Your muscles atrophy(also not sure what you meant) and you feel like a prisoner. Another downside is the addiction of playing. Computer games can be a real drug. They are able to attract you like a magnet with a strong magnetic field.
However, if you think for a minute how much time you have lost in front of your computer, you will feel as stupid as a bot(did you mean robot?). In spite of that, why not try learn English from the games we play. To be honest, I have learnt a lot of words and expressions. I can even say that some games have helped me set the foundation for learning a language.
