virtual work experience check out BSMS and ObserveGP
actually if you check Scottish medical schools, there are no subject requirements for AH only for National 5 and Higher; they only have grade requirements of 3Bs or 2Bs (Glasgow is weird in that if you take 3 AHs the offer is 3Bs but if you take 2AHs + 1 crash Higher then the offer is AB at AHs + B in crash higher)
on the other hand if you are interested in medical schools in England/Wales/Northern Ireland then they explicity state they want AH biology and chemistry alongside another science at AH all at As
I know people who got in with AH bio and chem + higher psychology; another one with AH bio, chem and music, someone else with AH bio,chem and english for Scottish medical schools
