If you want to do life science based research, a biomedical science degree that isn't accredited would probably be your best bet as this would entail much more flexibility with regards to your options.
An accredited degree has to meet certain standards by the IBMS (Institute for Biomedical Science) in terms of course content in order to make the graduate eligible to register as a biomedical scientist after their degree (and a period of training). This means there are only limited, if any, optional modules one can take with this type of degree - it's the one I'm on as I am hoping to work in an NHS lab as long as I can secure my placement for next year!
Anything that involves working in a lab! This includes biomed, biological sciences, biochem, mol biol, etc
I'm' so excited.
