Hi, sorry if you get the same response from me as prior responses have said but I thought I'd put a response in which may be less bias than official reps (no offence).
I have both my BSc and MSc in Biomedical Science (2018 and 2024 graduation dates respectively) and can say the way you study Biomedical Science is VERY different than you would study A Level. Personally, I found A Levels the hardest things I've ever done IN MY LIFE and would never repeat them as I effectively failed them (only A Level I got was a D in Biology, failed Chem and Maths spectacularly).
Full story here:
https://www.thestudentroom.co.uk/showthread.php?t=7619124&pAnyway, the way you learn in university is very different to how you would at school as you are expected to do A LOT of self study, particularly in Biomed as, if you just repeat back to the lecturers what they have taught you, you won't get any higher than a 2.2 (translation, you have to research diseases and clinical markers not mentioned in your lectures as well as mentioned content). It's also VERY important to blend one thing into another as, I went to UWE and specialised in Clinical Biochemistry, you have to perform differential diagnosis i.e. what the disease can't be based on patient results, clinical history and recommend different tests to determine what the condition can or could not be based on clinical presentation and the sample results given.
Also, with respect to open exams, SOME universities allow this (UWE did), at least with respect to my exam in Jan 2024 as it allowed us to take in whatever we wanted as long as it could fit into a folder, however, DO NOT rely on it as it's actually a hinderance (use it for useful facts not stated in lectrues which are hard to remember i.e. reference ranges, particular diseases for names you can't remember etc...). The exam may be 3 hours long, but sitting there reading when doing an exam is not easy as you're effectively meant to be writting for 3 hours straight and my MSc exam had 5 pages of hand-written A4 size content in it...
My BSc (may not be the same, it was a while ago) had an option where the examiner COULD tell us the second question, however, if she did, she would be much, MUCH stricter on the content (it was to write down the pathogenesis of a specific disease, in my case, haemochromatosis as it could have been any disease mentioned in the course otherwise if she did not).
Happy to answer any further questions you may have (I have some final year exam questions as examples if you would like one or two as examples) about the course in general.
Also, one final thing. If you want to work in a clinical/diagnostic lab, MAKE SURE YOUR COURSE IS IBMS ACCREDITED, as you can't work in a Band 5 post or higher without it, no exceptions. Unless of course you're willing to do top up modules (further time and money spent at uni after graduating).
EDIT:
Currently I am a trainee BMS in a Clincal Biochemistry laboratory but hope to have my full government registration before the second half of 2026. =)
