I am currently 22 years old, I graduated in Biochemistry and am now finishing my Master's in Bioengineering and Nanosystems, both with high grades. I've been thinking of leaving life sciences since I've rediscovered my passion for Physics (and Philosophy). Having some background on classical mechanics, physical-chemistry and electronics, how can I start a career in Physics? I'm thinking about applying abroad for a 1/2 year Master's in Physics (in UK), for which I need some background in electricity and magnetism, classical mechanics and introduction to QM; after the Master's, I would be apt to apply for a phD. -Is there any other way to shorten this path? I've read in this thread that to apply for phD in USA I only needed to be successful in GRE tests, but I don't feel like I should ingress before I am sure that I will complete it successfully without wasting years acquiring background. -Given economic limitations I was thinking of preparing the background needed for the MSc independently. Are there ways to refer this study such that it'd be recognized by an educational institution (e.g. online courses)?
