Hmm... Bring a computer in class? :P
Seriously, though, all I can do is wish you good luck. :)

well my physics test was today .. i solved pretty good
thanks god :D
but the main tip i can say is UNDERSTAND what the question offers you .. don't just memorize the equations and BAM the answer
if you understand the concept like freefall in your case .. you can pretty much "guess" the rule
when Calculating Keep in mind a Close~ answer
physics is fun tbh .. better than chemistry in lots of ways .. also Hard questions solve them first to keep your mind trained
and just in case if you forget a rule .. you already solved the hard one
i learn it in English but it's not my Main Language .. but i pretty much just understand the concept and write in my way
but first thing to do now is get off computer and STUDY :D

I did mine yesterday!
The only tip I can give you is to buy an exercise book and solve/understand as many problems as you can. Practice will help you remember equations and mathematical demonstrations; it's not simple but with hard work anything can be achieved!

If you don't intend to be a physicist, then I dunno :-P Try writing them down in a small piece of paper that you then smuggle out of your pocket. If you get caught, it's gonna be a bad day though.
If you do intend to be a physicist, then try to understand the concepts behind each equation. You will then be able to actually derive the equation when you need it without having to memorize it.

Memorise equations and replace them with values. Ideally you should have started revision way earlier, but last-minute cramming of equations does help a bit.
After reading the question, write down the values that you already know (eg. inital velocity u, acceleration a, time t) and what they are asking for (eg. distance s). Try to remember the equation (s= ut + 1/2 at^2) and find the answer.
Repeat for all topics. :)

l2p noob
Just kidding, aren't you allowed to take a book with formulas into the test?

Many physics text books I've seen list all variations of the same equasion, ie. Resistance (ohm) = voltage (V) / current (Amps), Current = voltage / resistance, voltage = current * resistance.
Physics teacher explained how to deal with that in a simple way: Remember only the one that's defined in the physics law. (ie. Ohm's law states only that Current = voltage / resistance). Rely on your math skills to work out the others, as it's just equasions to solve.

Memorize physics related jokes ;p It always helped me ;p
Heisenberg and Schrödinger get pulled over for speeding.
The cop asks Heisenberg "Do you know how fast you were going?"
Heisenberg replies, "No, but we know exactly where we are!"
The officer looks at him confused and says "you were going 108 miles per hour!"
Heisenberg throws his arms up and cries, "Great! Now we're lost!"
The officer looks over the car and asks Schrödinger if the two men have anything in the trunk.
"A cat," Schrödinger replies.
The cop opens the trunk and yells "Hey! This cat is dead."
Schrödinger angrily replies, "Well he is now."

Keep track of the units. If you keep all the units in your calculations it's easier to figure out how to get to the answer (even without knowing the formulas) given the information you have. It also helps minimize mistakes because if you end up with a wrong unit then you have obviously done something wrong. I had a teacher who called this legalized cheating.

Hey,
got a physics class test tomorrow and it's really hard to keep all the equations in mind. There are like 30, it's all about stuff like mechanical work, free fall, friction, energy forms, about impulse, power and some stuff I don't know how to say as I don't learn physics in english language. So yeah, just want to say: It's quite too much to keep it simply in mind, anyone got some nice tricks maybe? :P
