Context in admission decision

Now I have questions regarding with the admission–context. Compared with some students from big cities, their high schools are familiar to admission officers, their backgrounds are richer and their standard tests could easily gain high scores with the experienced training. Apart from the location, some poor families will have disadvantage compared with rich ones as the rich family is more convenient to access different resources. I would like to know what I should do to avoid those disadvantage to help admission officer understand my growing context because I believe that I could do better if I was admitted. Look forward to your reply and thanks very much.

Are you an international? That will make a difference.

Yes, Thanks for your answering.

You need to make sure your guidance counselor (or, if international, the head teacher, the principal, the magister, the head of form…) fills out a detailed profile that explains what your school is like. For instance, s/he’ll need to document whether there are advanced-level classes, whether you can choose them, whether you have a prescribed path; if a typical student has a 7 in your school, does it also mean they’re likely to get a 7 on national exams, or will they get a 6, or 9-10? If the former, your school has grade inflation (ie., your grades are higher than they should be compared to the national scale), if the latter, your school has grade deflation (ie., your grades are lower than they should be compared to the national scale.) Are there clubs? Whate are the types of honors? What percentage students go on to university - 100%? 30%?

The school I studied in just provide the same courses to all the students. The transcript just shows the subjects and the scores I got. I want to know what my head teacher could say? Do you know the common application? Could you take that for example?

I told you above what your headteachers must say - you need answers to the questions above.
