Hello, I have a few questions regarding acceptance to master's programs in physics. I started undergrad many years younger than my peers (I was 14). Due to a combination of poor discipline and time management skills, family issues, and mental health issues, my performance during my first three years of undergrad were lackluster (physics GPA - 3.0). I stopped slacking off in my senior year and made a 3.9 GPA my last two quarters, but having no research experience outside of labs (currently reaching out to professors and in the hopes of getting involved), I don't think going to a PhD program would be feasible. I'm wondering, how selective are terminal master's programs in comparison to PhD programs? if I were to do a master's and do really well in terms of grades and a thesis, would this open up a path for acceptance to competitive PhD programs? and could anyone recommend schools that are decent for theoretical particle physics that offer a terminal master's? I've only found a few so far. thank you in advance.
