Confused Brit looking for advice

[allvia]

that would be the ideal time for me to get a WES evaluation done I guess and see what I have that is transferable to the various degree programs.

The Open University is already a US RA school, I don't see why you would need to have a WES evaluation

I understand that, but I may also be misunderstanding the process a bit - maybe it's not WES but the individual universities I need to approach to evaluate how they would match the courses I've done to their class requirements?

You would apply to TESU for the BACS (for example) and then send them your transcripts from Open University. The application is $50 for TESU, and once they get your transcripts it takes them a few weeks to evaluate.  Should they question the credits on the OU transcript (I don't think they will, although sometimes you just get a confused TESU advisor), you can politely remind them that OU is a US RA University. For you it is pretty straight forward because you only have credits from one place (if I read the original post correctly); you're just a transfer student from one US RA to another US RA school. Once you have the offical TESU evaluation of where you stand on the BACS we can easily help you fill in the rest - quickest options, and lowest costs to you.
