University of sharjah is good but just ok. I cannot deduce if you are a girl or guy but if you are a girl then the best medical college in UAE is Dubai Medical College for Girls. Excellent!
and then there is GUlf Medical College Ajman which is good and there is college of medicine and health sciences in RAK which is good too.
But if you have the grades etc and want to stay in DUbai and you are a girl or guy then you go for this...
