Just an advice. I feel like if you're going to pursue a higher degree, go for something like med school over a PhD; they don't make alot of money.
In the UK its a standard 6 years of university as part of the formal medical degree. In my industry I can progress by taking accreddition courses. I don't need to do a masters its just on my bucket list.
I don't have the patience or discipline to study anything as intensive as medicine. Not my cup of tea sis.
