Integrated masters or bachelorsWatch
Also wondering if it would be a possibility to do pharmacology up until year 3 then change to an Msci course but obviously this is sounds slightly unrealistic.
SF allows 4 years of funding on an undergrad degree. There is also separate SF funding for postgraduate Masters degrees.
So 3+1 or 4 years - makes not difference.
Switching between MSci / BSc etc varies by Uni - check, email the Dept if necessary to find out their attitude/procedure.
