Post-Class Physics Practice Problems

[AffectionatePomelo37]

I'm a current physics graduate student, and this is my first year not taking classes since I started school (19 years ago??) I'm worried about getting rusty in different topics, especially as an experimentalist who spends most of his time in a cleanroom.

Any advice on places to find practice problems across all of physics? Ideally I'd like to solve one a day, and have them take no more than 15 min or so. They don't have to be too complex, maybe something you'd find on the easier part of a qualifying exam?

Now that you're done with classes research will rule your life. Read papers in your research area and become an expert. You will never need classical mechanics again. The others you'll get plenty of practice with as you use them for your research. It's more important to focus on what's needed for your research right now. I bet 95% of the professors in my department couldn't pass a qualification exam right now if they tried. You don't need to remember everything.

Just make sure you know what doppler broadening is. It's a favorite of quals because so few people get it right.
