Hi Bung Ilham.
Here are my suggestions to improve your score in the writing section. In this moment, I have a tendency to focus on your contents in this writing.
pros and cons
This tends to be used in the informal writing. You are supposed to deny that.
Actually, you have passed the task achievement well. It is proved with your essay free of the prompt wanted of the question. What you mentioned in the introduction has been explained in the body paragraph.
as good education and for parents like little strain of family budgets
you explain:
Child without siblings can perform better in their study
However, there is an odd thing. You should explain clearly why the child gets the good education.
"IT IS BECAUSE THERE IS A CONDITION WHERE THE PARENTS LOCATE INCOME FULLY FOR A FEW OF CHILDREN SO THAT THEY CAN SELECT THE BEST INSTITUTION".Turning to the second of the benefit and drawback sides in the body paragraph. You did not discuss deeply. That should contain the example as well. It will seem unbalanced. It is better if you decide to make one idea paragraph rather than multiple ideas vaguely.parents of a small family will see less pressure on budgets
Apart from that, you have shown the huge progress. I suggest you provide much to read the example. As many as you read the example of writing task 2, you will improve your flow in the essay.
OVERALL, IT A GOOD JOB
GOOD LUCK FOR NEXT TERM
