Applying to Italian universities as non EU studentWatch
In Italy there isn't the UK 'A"-level score, just a final "leaving high-school score" though Italian students tend to specialise, and choose which of the four types of high school they go to with a thought about later doing science & technical studies, or administrative studies or art etc
Classics School: literature, philosophy and history.
Science School: physics, chemistry and natural sciences.
Fine Arts School: drawing, sculpting and painting.
Technical Institute: agriculture and commerce
fees in Milan, near me, can be between EURO 3000 per year and EURO 17000 per year, as some are Italian State Universities and some are private universities, that is for EU and 'home' students, I couldn't find extra-EU with a quick check - guess 25K?
here's an explanatory page from Milan University http://www.unimi.it/ENG/courses/29553.htm
and note that 'foreign' acceptance school results info is PDF's 1 & 2 on this page http://www.unimi.it/ENG/admission/29528.htm
and note that extra-EU students should speak Italian (I learnt in 3-months approx) but also pass an exam, ~ 1 year of study.
and extra-EU require this page for a pre-application purpose http://www.unimi.it/ENG/admission/31192.htm
they mention for British/extra-EU students "(GCE) & International Certificate of Education (IGCE), rilasciate da enti certificatori ufficiali del Regno Unito, consentono l’immatricolazione se attestano il superamento di almeno tre materie a livello avanzato (A level) attinenti al corso di studi richiesto, con una votazione almeno sufficiente (passing grade). La presenza di un A level in lingua italiana sarà richiesto solo a studenti con cittadinanza straniera"
that GCE & IGCSE A-levels should be "passing grade" , need at least THREE in the correct subjects, and if you are extra-EU, then a FOURTH pass in Italian 'A'-Level would be needed. (UK kids might need this also, next week, depending on SHhhhhhh....)
further they say that there are quotas for medical applicants, but I have met quite a few extra-EU doctors in Italy, so paths do exist, or have existed
write to, for example, unimi.it and ask for their help, I'm sure they could offer some advice. I think you need to focus on the sort of place where you might get to, and follw their (possibly changing over time) requirements.
good luck and best wishes in any case ( I use university of Milan as a reference, partly because Milan is the 'industrial capital' of italy, with extremely sensible people - whilst the capital Rome also has universities, but life there is probably more expensive, and a bit more chaotic )
