Hi, Parklot,

What level of macro are you studying? I agree 100% with Kinma. (I’m an econ grad student)

Two suggestions:

1: Visualize the math!

2: Use mnemonics for non-math things that you may need to regurgitate.

- Ultimately, math is something we need to be able to understand and apply, not associate with an ocean of baby chicks flooding out of a kitchen sink like xkcd red spiders. Thankfully, though, mathematics has structures within it that act as mnemonics themselves! Often, in the long term, the best way to remember the which sign to apply to each term coming out of an integral is to visualize the integrated function as a curve, etc.

Or for elasticities, let me present the following exercise: visualize the image of a constant-elasticity demand curve, a linear demand curve, and a concave (concave-down) demand curve, and color up the graph to vibrantly remind you why the concave one is more price-elastic demand at high prices, and is more price-inelastic at low prices, both because of the

Basically, this advice sums up to the following: Ask your grad student teaching-assistants to explain mathy stuff to you using graphs and drawings.

- On the other hand, a lot of our graduate-level exams (which I am thankfully done with) required the preparation of different kinds of mathy proofs. So using the method of loci to efficiently list the steps of how to prove some of the more fundamental results I needed could have helped me save time studying proofs. In retrospect, I realize that I would often condense a proof onto one page, so that then the organization of my writing on the study sheet itself would effectively act as a memory palace!

For topics covered in a more survey fashion, one important thing was memorizing the correspondence between different sets of assumptions on the one hand, and the resulting model results after characterizing the model on the other. That could be accomplished with our meat-and-potatoes method of loci, etc.

Cheers,
