Your teacher who is writing your UCAS reference will make a point of highlighting that, and if your A-levels are good, it will make you look even more attractive to universities, for the sheer effort you put in.
For example, the first paragraph of my reference was:
"(Jamerson) studied for his GCSEs at __________ , a school put into special measures by OFSTED as he completed his GCSEs. By 2013 (Jamerson) had joined __________ School to achieve the highest grade of any student in his year group and was the only student to achieve 100% in his A2 Philosophy of Religion examination. I have worked at _______ School for six years and in this time encountered a number of highly able students, even amongst this elite group (Jamerson) stands out. It was not just that (Jamerson) read widely, which he did, regularly drawing upon the works David Harvey, Owen Jones, Noam Chomsky and Charles Hartshorne to name but a few, but it was the way that (Jamerson) used the ideas of these thinkers that makes him the most talented student I have taught. He was able to draw upon arguments from disparate fields of study to produce engaging, controversial and yet persuasive arguments."
