Teacher: Now, understand the problem? Solve this instance: [header] How to help your girlfriend study [title] Determine her optimum study time. [step] No matter how committed your girlfriend is to studying, there's going to be a certain point when she starts getting bored, losing focus, or becoming distracted. For example, she may be able to study for 45 minutes without her mind wandering. <sep> (A) Remember, however, that as her studies progress, there's going to be a time when your girlfriend is mentally ready for a real study session. [substeps] Ask your girlfriend what she's used to studying. (B) Point this out to her so she can study in the most effective blocks of time. [substeps] Your girlfriend may need help recognizing what her optimum study time is. (C) Take up this time by watching and listening to her work until she stops studying. [substeps] For example, let's say she always takes a break from studying to practice on a friday afternoon. (D) Studying for 40 can set her up for a slide class that includes cognitive reasoning, problem-solving, and visualization techniques. [substeps] As you might anticipate, dealing with a lack of her studied time can force your girlfriend to push aside the time and energy needed for her study sessions.
