Hello, I currently have an undergraduate degree in physics, with a slightly subpar undergraduate GPA (didn't take it seriously enough, but the real world and bills due is a good motivator now). I want to make up for it by doing well on the physics GRE, and applying as a post graduate with aims for a Master's degree. To do so, over the next 6-8 months I will be going over ALL of my old undergraduate material (I now have a job that has much downtime, I can basically focus on it for 4-5 hours a night reliably, 4 days a week). To get ready, I want to know what areas if any I should specifically focus on. I decided that the first subject I'd go over is Math Methods in the Physical Sciences. Within this subject, we went over: complex numbers vector analysis fourier series ordinary differential equations partial differential equations Would this cover everything I should know as an undergrad (I also have taken mathematics up to an undergrad degree, but never bothered to finish a senior project req for that major)? I don't question my undergraduate curriculum, but other chapters in the book cover other things that I could look at as well: infinite and power series linear equations and matrices coordinate transformations and tensor analysis calculus of variation gamma, beta,error functions and asymptotic series legendre polynomials and series solutions to diff eqs, bessel functions complex variables integral transforms, probability After I complete this I will focus on classical mechanics, qm, e&m, optics, thermodynamics, modern physics. I took other classes such as electronics, nonlinear dynamics, general physics, but will I need to focus on these subjects for GRE or graduate study?
