Over the years I've found this little trick that helps get my homework done faster. I can't really tell you what subject this works for because this opportunity can present itself in any subject. It just has to be the right type of assignment.
I think of this trick as myself being a factory. I think this because I don't do the whole problem at once. Instead, I do the first step of every problem I have, and then I do the second step of every problem, and then the third and so on until all the problems are finished at once.
For example, pretend there's some weird math formula where in order to get the answer, you have to multiply the number by -1, add 50, and then divide by 2. Say I have to do this for these five numbers: 5, 15, 23, 30
Instead of starting with 5 and going: -5 --> 45 --> 22.5
and then doing the rest of the problems, I would go like:
-5, -15, -23, -30 --> 45, 35, 27, 20 --> 22.5, 17.5, 13.5, 10
Another example would be when making Spanish/English flashcards, instead of writing Hola (flip card) Hello and then Adios (flip card) Goodbye. I would go Hola then Adios (flip pile) Hello then Goodbye.
I hope by now you can understand what my little trick is. It's hard to explain but can be useful once you get it down.
