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. We would advise against doing so, as you may be preventing another deserving student from taking part in Pathways or Access Apprenticeships, and it will not be guaranteed that you'll get a place on the UK Summer School or US programme instead.
