PA -> Med

If I don’t get into Med after reapplying and do physician associate studies, can I apply for graduate entry medicine or is this course not accepted/seen as having a different motive than med?

Since PA leads to a similar type of role but less of a managerial responsibility.

In principle quite a few aspects of the role are different and not purely in managerial areas.

In any event, if you're absolutely focused on doing medicine as in this case you would be better off just taking a gap year(s) and reapplying (and retaking in that time if needed). It will take longer and cost more (including out of pocket) to go down the medicine as a graduate route (either for GEM or standard entry medicine as a graduate) and it's much more competitive than standard entry medicine as a school leaver.
