<p>Is it necessary to memorize the values for all of the constants for the test? Will they be needed?</p>
<p>I did the May 2011 SAT Physics tests and I can’t remember being startled by any questions where I needed to know a constant.</p>
<p>You will be far better off spending your time on concepts rather than constants. Obviously, you need to memorize all of the equations. This helps with understanding the concepts too.</p>
<p>Can you use a TI-84 graphing calculator?</p>
<p>You may not use any calculator.</p>
<p>You can’t use any calculator. The proctor will know because he/she will have specific instructions stating that the use of a calculator is forbidden.</p>
<p>Besides, you don’t need one anyway. The calculations are very simple. The hardest part about physics is the concepts.</p>
<p>I’ve always wondered about the calculator thing.</p>
<p>Can’t you technically say that you’re taking math I/II and instead take physics/chem? I took the May test and all they asked was whether you were taking a math exam and never checked the actual test you were taking.</p>
<p>^You can, but that’d be cheating.</p>
<p>I heard somewhere that we should memorize the value of the speed of light. Is that true?</p>
<p>Uhhh, it’s not exactly difficult to remember. 3 * 10^8</p>
<p>^^Honestly, if you’ve done enough practice with physics, you should know by heart the speed of light, vacuum permeability, and charges/masses of protons and electrons (bonus points for mass of neutron).</p>
