Do you get stuck on an ACT math question and waste tons of time? Could you backsolve more efficiently? Do you freak out at the end of the math test because the problems are difficult and you're almost out of time? If so, this episode is for you.
If a problem is getting extremely long and difficult, you are approaching it the wrong way. You should stop working and decide whether to approach the problem another way or simply guess and go to the next problem.
On trial and error problems, start with the middle choice if the choices are in order from least to greatest or greatest to least, and start with the last choice and work to the first choice if the choices are random.
In general, the problems get harder as you take the test. You may want to start with problem number 60 and work back to problem number 1.
