i am currently a highschool student in egypt , and due to the stupid difference between education systems , the high school certificate from egypt is only equivalent to the GCSEs in england , so if i do go to england , i will have to spend another 2 years of my life taking high school AGAIN but thats not only it , i will have to wait one more year to gain home student status which gives me the right to apply for a university student loan * note : i am a british/egyptian citizen * , so i will be doing undergraduate school at the age of 21 !! does starting university at 21 give younger students an advantage over me ? specially if i succeed and make it to the phds , i will probably finish my phd in my early thirties while there will be other students who finish it at the age of 27 ! or should i study physics here in egypt , then move on to get an MSc in england ?
