## So glad I don't have to take the Physics GRE again.

• Imagine you are sipping tea or coffee while discussing various issues with a broad and diverse network of students, colleagues, and friends brought together by the common bond of physics, graduate school, and the physics GRE.

### So glad I don't have to take the Physics GRE again.

I wandered into a now little-used portion of my hard drive and realized that I'm done with the physics GRE and can delete the four example tests! Yeah!

One of my difficult subjects is E&M (probably cause I never took the undergraduate class in it). A new arXiv preprint shows how to write Maxwell's equations using geometric algebra, one of my favorite math tools:

$\Box F = c \mu_0 J$

There. Much simpler. Now I can do E&M problems like a champ.

Bring the qualifying exams on!
