Attention Redditors, my students, blog readers, and everyone else: just because you finished a practice test does not mean you’re done with it!
You are done with a practice test when you can not only do, but explain, every single question on that practice test. You can explain, at the drop of a hat, why the right answers are right and the wrong answers are wrong.
This should be true even if I wake you in the dead of night and ask you. While you are still blinking the sleep out of your eyes, you should be able to tell me the exact process to get the right answer and avoid all traps.
If you are not at that point with every single question on the practice test, you are not done with that practice test.
The same goes for questions, chapters, books, and flashcards. If you need help getting to that point on any question, try using an error log.
