tl;dr : find high quality questions. Do them. Wrong ones go in 21st Night, and then redo those questions.
21st Night is perfect for studying for standardized tests. In fact, that’s what I originally designed it for as a test prep tutor.
Here’s how you use it.
1. You’ll need a pool of high quality practice tests and questions.
By high quality, I mean similar in complexity and difficulty to the standardized test.
Preferably these questions and tests will come with explanations, but, if it’s a popular test, you can probably find explanations online.
2. Take an initial practice test to figure out where your strengths and weaknesses lie.
You’ll find it easy enough to diagnose your own strengths and weaknesses if you put the questions in 21st Night. Copy-paste the questions, then fill out the categories and subcategories. It’ll help if you know how the exam itself subcategorizes.
Open up the Google Sheet, and look at the patterns in the subcategories to figure out your strengths and weaknesses.
3. Look up the explanation to each of the questions from the practice test. Type the explanations into 21st Night.
In the explanations, you’ll want to try to “extend” your explanation, and think about how you can generalize your strategy. Or, in other words, don’t just put what to do, but also put why you do it.
4. Now, move onto the practice questions. You’ll want to find questions that address your weaknesses.
Any questions you get wrong, put in 21st night. In the explanation, again, try to generalize your strategies for future questions.
4.5. Do a lot, lot more practice questions. You’ll need to get a ton of questions wrong (and then learn how to do them correctly) before you’re ready to ace the exam.
5. Once you’re confident on all the similar questions, take another practice test.
6. If you’re not satisfied with your score, go through steps 3-5 again.
