I came up with the following general rules, and

**Since no specific course description was given, I am looking for advice that applies to pretty much any physics subject.**

*am wondering if others want to add to my list?*

- Be familiar with all the equations you are being tested on, so that you can quickly figure out which equation or equations will apply to any particular problem. Corollary: know which equations do
notapply to a given problem.

Example: "A wire carrying a current of 2.0 A is at 90 degrees to a magnetic field of 5.0 T ..."

In this case, realize that equations dealing with currentIand magnetic fieldBare relevant. Moreover, equations dealing with a chargeqmoving at velocityvare not relevant.

- Be able to draw a diagram to show what is going on pictorially. An example of this is using a free-body diagram to show the forces, including directions, acting on an object.

- Read the problem carefully, so that you are aware of all information that is being given you. Sometimes purely verbal information is actually conveying
numericalinformation. Example: "An electron ..." means "a charge withq=-1.60x10^{-19}C and massm= 9.11x10^{-31}kg..."
