Hey Samuel, thanks very much for your informative reply, it's much appreciated. I've chosen Languages as that degree has always interested me too, and I already have a basic understanding of Spanish, whereas I thought that if I did anything science based with the OU, I might struggle as I haven't practiced anything like maths for years, I'm worried that I might find it difficult.
I see what you're saying about the speaking practice, but maybe doing language exchanges on Skype could help out with that?
Very interesting about the access course at West Herts, would I have to pay for that? I would need to sort out work, because that's on Mondays, and currently I work on Mondays. Also, would the access course alone be enough, because I emailed a few universities, and they stated that I would need the access course in science and GCSE (or equivalent) level in maths. None of them stated that I could use OU credits to be accepted.
To be fair, if I could study with the OU, I would do, as long as the credits could lead to doing a degree in Marine Biology. The OU don't offer a Marine Biology degree, only a Natural Sciences degree, but I'm guessing that won't be as good as attaining a proper degree in Marine Biology.
Oh it's all so confusing, what with so many options! I received my loan declaration form through the post today for the Language Studies Degree with the OU, which it says I must sign and send back immediately, so is it too late to change things now anyway?
