How can I improve my problem solving speed for tests and competitions?

AI Thread Summary
To improve problem-solving speed for tests and competitions, dedicate one hour daily to practice and focus on timed sample competitions. Carefully read each problem and define variables clearly, as each sentence often corresponds to an equation. Identify problem types you struggle with, learn the necessary concepts, and seek additional practice problems in those areas. Familiarize yourself with specific topics relevant to the competition, such as geometry theorems or algebra tricks. Consistent practice and targeted learning are essential for enhancing performance in timed settings.

Does anyone have long-term advice for becoming better at timed problem solving, such as in a test or competition setting? I can dedicate one hour per day 5 days/week to train.

Read the problem carefully. Clearly define your variables. Typically each sentence can be translated to one equation.
 
Thats not exactly the type of advice I was looking for...

Has anyone here been involved in competitions at some point? How did you practice, and did it work?
 
Practice by... practicing. Do some sample competitions (usually you can get older versions of the test) and see what kind of problems come up. Some you'll know how to do, some you won't. Pick out the ones you don't know how to do, learn how to do them, then find more problems of that type to practice on. It depends on what kind of competition it is, in high school a lot of them were big on geometry so learning obscure theorems involving circles and secants were worthwhile, depending on what kind of test you're taking different subjects will be important to know
 
Learn algebra tricks. Learn your trig identities. Memorize the Taylor series for common functions. Memorize Gaussian integrals.

And practice.
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
Thread 'Video on imaginary numbers and some queries'
Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...
Thread 'Unit Circle Double Angle Derivations'
Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...
