Forensic pathologists

Do I have to go straight to med school or go uni and get degree in forensics science / biomed science then get degree then go med school?

What do you want your job to look like?
Do you want to be involved in the patient-facing*, clinically oriented aspect of forensic pathology? Where you'd need to be aware of the rest of medicine and surgery in order to come up with a diagnosis/report? Performing post-mortems, being questioned in court about cause of death etc? Then, yes, you need to study medicine and histopathology specialty training.
*The patient is usually dead but that still counts 🙃

You can do either. Both can get you a degree in forensic pathology, as long as you do a degree in medicine (graduate or not)

Thank you , I think I will get my masters in forensics then go med school

Are you currently in sixth form? What A-levels are you doing/will be doing/have done? If you're doing the right A-levels, you can apply for the undergraduate medicine degree. It is much cheaper and significantly less competitive than GEM. Also if you're going for GEM, I would recommend just getting a bachelors in any subject (you can do forensics) and then applying for medicine - a master's degree would be extra time and money for the same chances into med school (For GEM, I don't believe most care what your degree is in or whether it is undergraduate/postgraduate)

Oh okay, im currently doing lv3 applied science. Would you recommend I go straight into med school? And how are the ucat exams like how do you prepare for them content wise?
