Take a 5-10 question qbank, on just one area you want to focus on. One subtopic. This is the only type of test you want to select “show explanations”.
As you go through the quiz, write down every word, phrase, or topic you don’t fully understand in the questions and answers. Then make your best guess as to the answer, and write down all the words/phrases/topics you don’t know in the explanation. Then move on to the next question.
