I recently moved back to the UK, but since I haven't been in the UK for the past 3 years, I will have to wait for 3 years to do an undergraduate degree. What's even more, my high school diploma, which is from Egypt, is not accepted to be equivalent to the British A-Levels, and so I am doing A levels at the moment. However, by the time I can apply to universities, I will be 20 or 21 depending on certain circumstances. Do you think my age will affect my chances if I apply to top universities? From a general perspective, do you think I will be expected to be better than the average 18 year old applicant, since I had two more years to be better or something?
