四节汉语课
半个小时前我有再一节汉语课。
===》半个小时前，我上了一节汉语课。这是特别的一节课，因为老师住在和我住在同一个的城市。===》（Pay attention to the order of the sentence. In English, you have two options to express: 1) Because the teacher lives in the same city in which I live. 2) Because the teacher and I live in the same city. In Chinese, you chose the previous option, it is understandable but sounds weird. So better to simplify the sentence, the second option.）
她是华人。我选她，是因为她是中国人还有她住在这儿，这样没有时差，我可以选课的时间更容易。===》（I am not sure about your mother tongue but you might also need commas for such a long sentence in English. ）
还有她的教学视频是很好的。===> (I am not so sure what you were trying to say about her videos. I suppose her teaching videos. Also, 是 means are. ==》 Her teaching videos ARE very good. I saw another Chinese took 她的视频 directly as video call??? Practically I don't know what a good video call is or say how to define a good video call. So I corrected your sentence according to my understanding.)
现在我知道她是一个好的老师。
我们聊天太好。我们笑很多。===> 我们欢声笑语，聊得很开心。
我越来越少怕跟中国人谈谈。===> 我越来越不怕和中国人聊天。（少怕 sounds weird. I am not afraid of xxxx==> 我不怕. The difference between 谈谈 and 聊天。谈谈sounds more serious. EXAMPLES: 1) the headmaster asked me to have a talk in his office. 校长叫我去他办公室谈谈。2) I need to talk to my psychologist this Sunday morning. 这周周日早上我需要和我的心理医生谈谈。 聊天 sounds more casual. EXAMPLES: Me and my friend had a nice chat/talk yesterday. 我昨天和朋友聊得很开心。）
啊我特别喜欢italki！
我们聊天普通的话比如说饭菜、学习、匈牙利的中国饭店等等。===》我们聊天的话题比较常见，比如说，饭菜，学习，匈牙利的中国饭店等等。
我学习到一些生词。
我们同意我跟同学们一起去吃中国菜的话我会问她！===》我们约定了如果我和我的同学去吃中国菜，我会问她的意见。/我会叫她一起去。（According to your next sentence, I think what you were trying to say was you and your teacher made an agreement that if you and your classmates go to have Chinse food, you are gonna invite her too. Please confirm.）
我很高兴，也我也觉得我的同学们会很喜欢她。===>（也 should never be used in front of the subject! It should be forever behind the subject.）
还有他们会有机会用他们的汉语！===》而且他们也会有机会练习他们的汉语。(What's more, they will also have the opportunity to practice their Chinese. )
