Please, correct my writing IELTS Task 1 Practice :)

The two pie charts compare and contrast data on the different seven study fields of post-school qualifications of two age categories; under 40 (25 to 34) and over 50 (55 to 69) in Australia.

In general, Social Sciences, Arts leads highly of the main fields of study than the other subjects.

More specifically, Social Sciences, Arts is the highest choice in both of two ages with a figure of 19,48% (age between 25 to 34) and 20,42% (age between 55 to 69). These contrast markedly in Architecture with 1,85% (age between 25 and 34) and in Veterinary,Agriculture at 2,0% (age between 55-69). However Veterinary,Agriculture is the lowest post-school choice in age over 50. Another side of levelable Australian's degree addressed Engineering course has over 2-fold percentage; 9,36% (from 357,500 Australians) and with 19,27% (from 104.800 Australians). Clearly result of two pie charts of the seven main fields of study social Sciences, Art become a popular post-school qualifications for more than 460.000 Australians.

you should separate into 2 paragraphs because it will be easy for everyone to follow.
Next, the way you give data is not good at all. i mean that you should put it in many ways and especially you avoid repeating words.

Before correcting, I would like to welcome you in this forum then some of these should be highly pondered further.
1. I suggest you to write in appropriate form. Commonly in Task 1 there are intro, overview and bodies.



How can I see those point ?


You cannot use past form as the reported years are not clearly written.


Check your subject verb agreement.

2. Remember to attach your reference picture,diagram or graph so we can examine whether or not your work is quite in line with the task.Even though grammar accuracy, lexical resource, coherence-and-cohesion are important, task responses is a must.

It takes some time to give some feedback, as this writing has no picture included. I suggest attaching the picture right now. Also, you need to rewrite this report writing, using this following structure:

1. Introduction: what does the chart show?
2. Overview / summary: what are the most noticeable features?
3. Specific details: try to write 2 paragraphs.
