hi guys! how can i remember these formulas?

Question

i will get my diploma this year and there is a hard exam which i have to pass inorder to enter to university and study medicine the time of this exam is 3 hours and there are 150 questions the questions are about biology chemistry physics math litrature earthology english arabic and you know this time for this amount of questions is not enough and so we have to solve the questions fast so we have to memorize a lot of formulas for example for math 150 formulas for physics 80 formul;as for chemistry 60 formulas for arabic alot of rules and i am worried becausei dunno if i can remember all of these at that exam what can i do ?please tell me what to do?

Answer 1

Find correlations between physical formulas, chemical drawings and arabic script. Also, why the heck do you need to know Arabic to become a doctor? I'm pretty sure mine doesn't.

Answer 2

I have four degrees, through PhD, and had to take dozens of exams that incorporated dozens of equations/formulas each. One way I got through them so I could use them during an exam was to study and understand the underlying physics, chemistry, etc., of each one.

For example, F = G Mm/ r^2 is the force proportional to gravitational attractiion between two masses r distance apart. The underlying physics is that this is an attractive force between two bodies, that the force diminishes as the square of the distance between them, and that the force is proportional to the multiple of the masses. With these fundametal laws, I am reminded I need two masses in the numerator of my equation, I need the square of the distance between them in my denominator, and I need a constant of proportionality that has (Newton m^2)/(kg^2) units.

Which brings me to another way to remember equations...pay attention to the units. Force is in Newtons, which are defined by kg-m/sec^2 So, for example, if you can't rememer if its F = m/a or F = ma, work out the units. F = m/a = Newtons = kg-sec^2/m <> kg-m/sec^2. Thus F = m/a is incorrect because you don't get Newtons (kg-m/sec^2) from it.

Finally, learn just a core set of equations, from which all the others can be derived quickly. I emphasize QUICKLY because you cannot afford the time to derive long, difficult equations, which will have to be remembered to finish in time.

For example, f = W - F is the core equation for net force acting on a body of weight W. But most problems have to be worked from f = m(g - a), which is a bit more difficult (three instead of two variables), but can be derived from the core equation for f. You also have to remember the physics when choosing the sign for a; does it add or subtract from the gravitational acceleration?

Answer 3

Practice enough problems where you apply these formulas again and again. Make sure you didnt miss any formula. It shoudnt be so difficult. Start practicing.

Just memorizing the formula is never going to help.

Answer 4

the only thing you can do and trust me on that is to know how to prove the formulas.
you will need to memorise some usefull and important formulas and then you can prove almost any formula at your level.
if you do not have the time and the important factor is to remeber them and remeber them quick then try to corralate formulas to specific problems. so when the problem starts you right immidietly the formulas and be on th safe side.

Answer 5

The equation of a line is in many situations in y=mx+b style, the place b is the y-intercept and m is the slope of the line. Given y-intercept is one million, the y=mx+one million you may locate the slope (ratio of upward thrust over run). you have 3 x-intercepts, the place there could be basically one for a linear equation. you may basically have those 3 with some style of sin(x) functionality. enable's take between the x-intercepts and resolve: Say (-3,0). the two factors are then (0,one million) and (-3,0). the upward thrust is the adaptation in y values; the run is distinction in x values: m=(y1-y2)/(x1-x2) = (one million-0)/(0-(-3))=one million/3 consequently, y=one million/3 x +one million you may do an identical technique with all of the different 2 x-intercepts to define those 2 strains.

Answer 6

If you make the subject your own, you start liking it, all formulas will become your second nature. Some formulas I learnt years ago I remember even today.

Answer 7

Often making up rhyems for them can help you remember formulas

Answer 8

The exam is to filter out people like you. So look for another profession.

Answer 9

Study. And when you think you have studied enough, then study some more. Do this daily.

Answer 10

store in your scientific calculator or else write on it in pencil it will not rub off, we use to do that
