first part:

Today’s world is in the (a) competitive age. Everyday is alive with challenges especially among children. They compete with one another for something in the endless race every day and night. And so the life of today’s children is too hectic to enjoy fully than that of the children in the past. In this essay, I will point out why children get stress and suggest ways of allowing children to grow up in a non-stressful environment.

1. Everyday is alive with challenges especially among children: ( some incorrect words)

Everyday has different/great/stiff challenges, especially for children

2. They compete with one another for something in the endless race every day and night:(simplify; article)

They compete with each in endless race every day and night

3. And so the life of today’s children is too hectic to enjoy fully than that of the children in the past.( some incorrect words)

So today's children do rarely enjyed the life fully, compared to the children in the past.

 second part:

From kindergarten to university, today’s children lives are too hectic. First and foremost, they have to go to school. In the classroom, sometimes they are under pressure and stressful because of the favor shown by their teachers. After school, they have to have ( two' have' here, could you chage another word? like ' pay extra tuition' ) extra tuition and other courses so that they can learn as many things as possible. Finally they arrive home and then they have to do their homework. This is the daily life of today’s children. Whether they want to do or not, they are being pushed all the time. The parents want their children to be well-rounded ones. They neglect what their children are actually enthusiastic in. They should understand the capacity of their children and realize that their children are not supermen. This is why, most of children are not happy at home and always under stress.

(I think you need some link words so that the readers can understand more well. I rewrite it in this way, hope you don't mind)

From kindergarden to high school to univerity, children today are living under great pressure. First, studying in classroom, they have to compete with their classmates for the favor of teachers. Then, after school, those who have fallen behind need  to participate in some cram schools, in order to keep pace with their elite peers. However, unfortunately, tons of homework are waiting for them when they finally return/arrive at home

HI, Moemoe

You are studying German! How brilliant you are! Is that cool? I heard it was quite hard to learn! Compared to English, which one is harder in your mind?

You definitely can do that! Band 5.5 is a relative easy score to get. I mean, you only need to achieve 5.5 in both reading and listening, and 5 in writing and speaking. It is not hard to score. Expecially in R. and L., you can gain a higher score than 5.5 comparatively easily. Of course, you need to practice! Just the IELTS 4-8 can be enough.

I think 2 months is enough. But now it is one month left. I think the best way you need to do is to get a higher score in your reading and listening, in order to balance your overall score.

If your minor errors in writting can be diminished, I think you can at least get band 5 in this section! But remember, do address all the questions in the essay topic, and don't forget to write above 250 words.

In terms of speaking, the most important thing is fluency. When the examiner asks your questions which you don't know, don't froze there and think too long! Say something! Even you are not so sure! Do your best to answer the questions immediately! Another very important thing——don't copy your answers from a IELTS book entirely. Because it seems like the examiers are good at identifying if you are reciting or not. You can use some ideas or words on the IELTS book, but use your own sentences to organise. If you do so, I think you can get band 5.5 in speaking at least, as long as you can make the examiners understanding most things you are talking about.

With regard to listening and reading, as I said above, just practise can help. Use the series of Cambridge IELTS. Be strict to time( 30 min and 60 min each). Then, after completing them, you should do intensive reading and listening. That is, you need to replay your radio until you figure out what they are talking about. Likewise, try to understand each sentence . In this way, your levels of R. and L. could be improve unconsciously.
