I am a high school student with a strong interest/aptitude in Physics. Recently, I have been considering the possibility of earning (remember, this is hypothetical) a Ph. D in Physics, but I am not sure of what is required, or what the coursework is like (whenever I look online, I can never get a good, definitive answer), etc. So, PF, I would like to know: -What are some good academic prerequisites? (When applying for the initial program, i.e. B.Sc., and then the actual Ph. D program itself) -What can I do to prepare for it? (mentally, academically, etc.) -What are the earnings? -What are the jobs that can be done with the Ph. D? (relates to previous question) -What is the coursework like? Does it vary from college to college? - ^Is it challenging? -Are good math skills really necessary? (Not saying that I don't have them...) -What is the final dissertation like? (poorly formatted question, lol) -Which colleges/universities have the best programs? -Are the admissions competitive? (another poorly formatted question, lol) And finally, probably the most important: In the end, is it really worth it? I would really appreciate your responses. Thanks in advance.
