Shakespeare says that "comparison is the thief of joy".
It may be that you are seeking some consolation for not doing well in your A levels by posting numerous threads in which you cast doubt on the achievements of others, as well as threads in which you speculate on ways in which you might game or even cheat the admissions systems of well known universities. It might be better instead to try to do better in resits, and move on.
The concept of "natural intelligence" is contentious in any event. A human born without developmental impairments has the potential to learn almost anything. Environment and education are critical in determining how well or badly a child does in academic tasks. Studying hard and revising for exams are not indicators of a dumb student who merely memorises his or her way to success. Study and revision are indicators of a well-organised student who appreciates that effort produces results. Very few people, if any, waft their way through life without making any effort.
