Which Access to Higher Education Diploma Would Be Best for A Languages Degree?

Hi,

First a bit of background. I've been self studying Japanese for a while now and have become quite proficient at it, I'd like to study in a more structured environment and so a degree seems like the next step. Problem is I don't have the best academic record up to this point and so I’d like to study an access to higher education diploma to improve my chances of securing a place at university next year.

So my question is as the thread title suggests, which access to higher education diploma would be best for a languages degree?

Through my research it seems that the Humanities Access Diploma would be the most fitting of the courses but I might be wrong. I’ve also seen that the Open University has an Access to Higher Education module that can have a large focus on foreign languages if the learner chooses the language units. However as this is a module and not a Diploma I’m thinking it might not be recognised by other universities.

Any input would be appreciated
