How do you know what to memorize

[ex.tern]

This might be a dumb question, but does anyone else struggle with figuring out which formulas or equations you're supposed to memorize cold and which ones will be provided on the exam sheet? I'm reviewing physics heavy sections and sometimes I can't tell if I should be drilling the equations into memory or just focusing on how to apply them, I don't want to waste time memorizing something that'll be handed to me... but I also don't want to get blindsided on test day

Is there a general rule for this? or does it just depend on the exam board or the practice materials you're using?

It is not a dumb question at all, tons of us wonder the same. Honestly, it really depends on the exam board. Your best move will be to check past papers and formula sheets then drill what's not given

One thing I've learned over the years is that no one should try to memorize every formula. First it's impossible, second, there's no point. Figuring out the concepts and remembering the basic formulas is all you'll need because you can get to the more complex ones through the basics and some rules. Even better if you're allowed to use a formula sheet.

@ex.tern, you just need to let the practice tests and official materials guide you. Treat every practice exam like it's the real thing. If the formula is provided on the sample exam's sheet, don't waste time memorizing it cold.
If it's not, you'll need to know it. Generally, the more obscure or complicated the formula, the more likely it is to be provided. The basics are almost always on you to remember.
