Is it possible for me to do btec applied science a-level in sixth form and then also do self-study as a private candidate for a-level biology ? Is it possible to have those two qualification or if i do applied science will i be able to do biology after? I want to do bio but dont have the gcse grades for that so am forced to do applied science(btec) , would it be better if i picked a different subject as an alternative to applied science and dont do that and instead study bio and chem a-level as a private candidate and dont question if it is wise i know ill handle it. or if i did do btec applied science and say after year 13 take a gap year and do a-level chem and bio is that possible or will it say i cant do a private exam on those in question as i already did btec science. please answer and thank you (want to do medicine in future)
