Can I gain an A Level without attending a college? For Dentistry related studies

Hi everyone, just looking for some advice please. I’ve been out of education for a long time now so I’m quite out-of-tune with it all. I’m a qualified Dental Nurse and have been for quite a few years now, but I’m considering progressing onto Dental Hygiene/Therapy at University. Most Uni’s I’ve looked at will accept Level 3 Dental Nursing alongside 1-2 A Levels in a science subject. However, I only have an A Level in English Language. My question is, I’ve noticed there are now things such as Open Universities where you can study from home. Is there an equivalent for A Levels, and are these recognised equally, also has anybody used any of these methods/what would you recommend please?

You can do a foundation year dental therapy course. Such as
https://www.plymouth.ac.uk/courses/compare/bsc-dental-therapy-and-hygiene-with-integrated-foundation-year/msc-restorative-dentistry
‘GCSE
Applicants need to achieve 5 GCSE passes (grade C/grade 4 or higher) which must include the following subjects:
English Language
Mathematics
One Science subject – awarded in either Chemistry, Biology, or Physics or Combined Science
Plus suitable Level 3 qualifications or experience as outlined below:
Experience in lieu of Level 3 entry requirements
At least 2 years in practice experience as a qualified registered Dental Nurse (proof may be required at the time of application). Applicants must have 2 years’ experience at the point of application
OR’… proceeds to list different level 3 qualifications.
For A Levels, there are many online providers, but some may only teach you, but you would have to find an exam centre yourself - The last one, open study college, the provider has exam centres.
