Besides the kinematics and projectile equations, what equations should we really know? I have the Kaplan Review Notes book and it has so many equations, it's impossible to tell which are very important. Any feedback is appreciated, thanks in advance

Hm, just off the top of my head:
springs ( F=kx, E=1/2kx^2, T=2pi sqrt (m/k) )
rotational motion (a=v^2/r, F=mv^2/r)
Magnetic fields/energy
Electric fields/energy (as well as capacitance, ex E=1/2CV^2)
thermodynamics
simple harmonic motion (ie pendulums, etc)
conservation of energy and/or momentum (elastic and inelastic collisions, E=U+K)
Reducing a circuit (resistances and capacitors)
fluid physics (ie pressure, density, buoyant force, etc)
Newton's Laws and the Laws of Thermodynamics are very important!
ETA: Forgot to mention that you have to know your light energy and lens/mirror info. Equations, converging vs diverging, what makes a magnifying glass, etc.
