I assume your talking about physics, so just food for thought...
2 years of a brick university is 9k + 9k + accomadation fees, maybe looking at 30k for year 2 and 3. Ouch.
You get a full honours degree with IOP accreditation either way, also going to a brick uni through open plus increases your study duration by 1 year. Ouch again.
If you want the uni experience, Have you thought about smashing out a undergrad degree then going for a masters?
