University of Birmingham say
here that for Biomedical Science, "BTEC Level 3 National Extended Certificate (or Diploma) can be considered in conjunction with the 2 science A levels." So two BTEC Extended Certificates and a single A level won't meet their requirements for that course.
The same page also says that, "Students who are eligible and successfully complete a Pathways to Birmingham programme will receive special consideration from admissions tutors and an alternative offer (typically two grades below the standard offer)". That "special consideration"
might provide the flexibility you need, but I suspect not given that their A level requirements are "Two science A levels from Biology, Chemistry, Mathematics, or Physics". So they'd need to (a) accept two BTEC Extended Certificates and one A level, and (b) consider
both "Applied Science" and "Health and Social Care" to be a suitable substitute for a science A level. That seems unlikely to me, although you'd need to contact the Biomedical Science admissions team (
[email protected]) to find out.
University of Worcester say
here that for Biomedical Science they have two sets of entry requirements:
"96 UCAS Tariff points MUST include A Level Biology, Human Biology or Chemistry and A Level in another science, Maths or Statistics."
"104 UCAS Tariff points MUST include A Level Biology, Human Biology or Chemistry."
The fact that they've put "MUST" in all caps doesn't bode well. However, they do say "Other qualifications, such as BTEC in Applied Science or equivalent, and Access to Higher Education (with at least 15 credits of Biological Sciences gained), will also be considered." When they refer to BTEC in Applied Science, they're probably talking about the Extended Diploma (worth three A levels), however. The bottom of that page lists contact details for the general admissions office, the course leader and an admissions tutor - one of whom should be able to clarify things.
University of Warwick say
here that for Biomedical Science, "We are happy to consider applicants who are studying BTECs alongside A Level Biology. We are also happy to consider applicants who have taken the BTEC Level 3 National Extended Diploma in Applied Science on an individual basis." As you don't have A Level Biology, and as your Applied Science BTEC is an Extended Certificate (worth 1 A level) not an Extended Diploma (worth 3 A levels), that would seem to be out.
Aston University say
here that for Biomedical Science, with respect to a BTEC National Extended Certificate, "With this BTEC you must also achieve grades BB in two A Levels of which one must be Biology."
Manchester Metropolitan University say
here that for Biomedical Science, "Other Level 3 qualifications equivalent to GCE A level are also considered."
So, based upon the information each university has published on their web site, Manchester Met looks like you best option out of these five. I suggest you ask them.
