Hi Luca Emma,
I strongly recommend you to read my writing carefully and question carefully!
Actually, it is convincing that the advantages of having this scheme outweigh the disadvantages.
This is my opinion, my clear position in my introduction.
introduction
1st para: support + give your opinion
2nd para: oppose + give your opinion
conclusion - summarise what you said + opinion. your conclusion is poor, rewrite it
I am sorry this is not the structure in IELTS writing. I disagree you that my conclusion actually is a poor one.
By the way, this writing already received a decent score. Anyway, thank you for your comment. If you know how IELTS writing should be like, then, you will know, some of your comment doesn't really make sense!
Cheers
