What kind of constants are absolutely necessary to remember?

I'm assuming that Avogadro's number, the gas constant, and the speed of light are absolutely necessary. I'm wondering if I should memorize things like the charge on an electron, Coulomb's constant, gravitation constant, and etc.

I haven't really seen them ever actually require you to memorize the gas constant... Avogadro's number and c, for sure. But tbh I wouldn't bother with those other constants. Can't hurt, but I've never come across a question were I had to actually know that off the top of my head. Seems a bit overkill IMO.

You should know k, 9x10^9 for electric force and field calculations etc. Also that 1 mol of a gas at STP is 22.4 liters.
