Use questions to understand better.
Test yourself. On everything.
All the time. Write out a problem by hand (don’t type), for example
write the problem on one side of a flash card and the solution on the other.
Writing builds stronger neural structures in the memory than typing.
Alternate different problem-solving techniques during your practice in
your focused period.
Never practise too long using only one problem-solving
technique – after a while you are just mimicking what you did in the previous
problem. Mix it up and work on different types of problem. This teaches you
both how and when to use a technique. Quiz yourself randomly on different
types of problem. Another way to do this is to flip randomly through your
textbook, choose a problem and see whether you can solve it cold.
During a lecture jot down questions about everything you don’t completely
understand. When you get home, find the answers.
Before you jump in and start doing, ask yourself: what is the real
question here? What am I supposed to learn from this exercise?
