Hey,I've a Physics exam coming up very soon.The problem is that I just can't seem to remember/recollect information when needed. Any tips/helpful points or notes would be appreciated. Thanks in advance.

    using my experience, the better thing is to solve many exercises as you can

    I find that understanding the concept and trying to derive the equations from mental experiments is one good way. A simple example is Pressure. What's the equation for this? Well I think, if I push harder, apply more force, then the pressure increases. Now I can either press my hand with my thumb or with a needle, both with the exact same force, but the pressure will be much greater with the needle. So smaller surface area makes higher pressure. So by these considerations we can recall, \[P=\frac{F}{A}\] now if someone says something like, "A man who weighs a mass m is hanging from a suction cup, what's the surface of the suction cup?" what do you do? Just go for it, write down all the equations you can and draw a picture of the free body diagram. If you're stuck it's better than nothing. Once you see it written out you can more easily recognize what goes together. So for instance, F=mg is the force of gravity pulling him down P=F/A has some things in it that we might need, area. So I'm not expecting you to have known this, but I think it's fair to say that air pressure is a constant value so we could look this up just like we looked up the value of g for gravity. Now we can plug one into the other and solve for the surface area A. Maybe this example is too simplistic but the point is that you can really get a lot of stuff done by just following the units and the equations, they tend to lead the way in some cases. Then once you've reached a point where things don't work out or when you've come to an answer you can check yourself with questions like, "Can an ounce of water hold 1 million joules of heat before evaporating?" Is this realistic or have I gone wrong somewhere?

    i draw things out, not just equations but general info. i have used this not only for maths/science/engineering but also in acquiring full legal (ie very wordy) qualifications. it has worked for me but we are all different. thing is, i like to hold as much of the big picture in my head, and then filling in the parts can be easy. if that is your mindset, you might find cheatsheets useful. they are all over the internet. find the ones you like. you get the big picture/ a lot of detail on a single sheet. depending on how much detail there is, practise scribbling it out yourself. eg https://docs.google.com/viewer?a=v&pid=sites&srcid=YWltcy5hYy56YXxjb21wdXRpbmctYW5kLWxhdGV4fGd4OjZjYWViY2NjOGViYzlkZjM then make your own. i think it works for me a bit like a mind map. i will have done the exercises, and so will be fluent, it's just a way of getting orientated and getting stuck in. sounds like that might be what you need to. there seems to an incredible amount of variety in how we function. some people like mnemonics. some kids use formula triangles: i don't see the point of them but that is my personal take. some people just have incredible memories and take their lead from that. there's also a huge amount of technique in actually sitting a paper. read the paper first, time it right, AND give them what they want rather than the best/ a good answer!!!! find your thing. it is there :p

    In all honesty, if you're one of those people, like me, who studies all night and forgets everything during the test, I feel your pain. lol What i do is take key info that I know will be on a test and write it over and over again. Call me crazy but it works. Doodles also help too. Just relax though. don't let the pressure of the exam take over your mind. Keep calm and study on... :)
