So, in the U.S. there are programs for students who have completed their undergraduate but lack the necessary prerequisite courses (or have an inadequate GPA and need to re-take these classes) in order to apply for med school. Although there are formal certificate-granting programs that are specifically designed for this purpose, many people simply take the necessary courses at a University in a non-degree setting.
I myself was an economics major but have since decided that I would like to study medicine and need to complete a few basic science courses before applying to med school. I was wondering if there were any such opportunities in the UK, either formal programs or a way to simply enroll in a University and take the necessary classes without working towards an actual degree.
