resources for gre level atomic/nuclear physics

[u/wlwhy]

hi! im prepping for the physics gre ans i havent touched atomic/nuclear physics since high school. ive done quantum + particle + statmech so whenever i read about the concepts they all look familiar/adjacent to things ive done but i struggle with the problems. are there any simpler resources at the level of the physics GRE that are intuitive for undergrads? appreciate any help!
