(This is a real IELTS topic that I found from website, however, it seems a bit odd in terms of academic subjects. How do people put the subjects into categories actually?
I like your way of thinking, Yoyo! I don't think they should be put into categories this way, either! But the question is a good one; it is all about what you think is most important in life. Science and math can help you get a job that pays well, and art can help you enjoy life in a deeper way. I think, because you believe this prompt is strange, you probably value art and music as much as other subjects. :-)
Kathy, this is great advice! It's true; the grammar is not bad, but we need more examples. I think every paragraph should have at least 3 or 4 sentences. Write paragraphs like this:
Sentence 1: Give the main idea you are sharing in the paragraph.
Sentence 2: Give an example to help the reader understand what you mean.
Sentence 3: Give another sentence to help explain it in an even clearer way.
Sentence 4: Give one final thought about the topic of the paragraph.
You do not always need to use the above method, but if you do it will help you to write good paragraphs.
