No, you can only apply to one.
Furthermore, once you’ve accepted your place on a programme, you will not be allowed to apply for another, even if you withdraw. For example, if your application for Pathways or Access Apprenticeships is successful and you accept your place, you will not be able to apply for a UK Summer School or the US programme.
However if your Pathways or Access Apprenticeships application is unsuccessful, or you decline your place, then you will be able to apply for a UK Summer School or the US programme when applications open later in the year.
