The requirements for Scottish highers for medicine are on the websites of medical schools. Generally for England and Wales you need to have done advanced highers (to be equal with A-levels) - either 2 or 3 to include chemistry and often biology. Scottish universities require at least 5 highers to include chemistry and biology.
Have a look here for requirements http://www.thestudentroom.co.uk/wiki...ttish_students
You need to sit 2, preferably 3 advanced highers, and you do not need so many highers - far better to drop at least one and sit advanced highers in chemistry, biology and another subject.
You would also need to meet their GCSE or equivalent qualification requirements, 2 National 5s is not enough.
I am doing scottish highers and advanced highers now but in fifth year i only sat three highers, however to get into medicine the entry requirements in scottish universities say tht you need to sit 5 highers in s5 and get 4 A and a B. Therefore is there any possibility for me to do medicine coz i will do 2 advanced highers in sixth year. Or should i consider applying for medicine in an another country???
For scottish unis, if your concern is that you took 3 instead of 5 highers in s5, you need to contact individual universities to see if they are happy to accept you taking the remaining 2 highers alongside your 2 AHs in s6 - I shouldn't imagine it would be too much of a problem as you are not applying straight out of s5, and you will be taking a high workload/a lot of exams in one sitting which is what they want you to demonstrate.
