#2-Grinding ProblemsLike the students who fall into the trap of believing that most learning occurs in the classroom, some students believe understanding is generated mostly from practice questions。 While you can eventually build an understanding simply by grinding through practice, it’s slow and inefficient。做练习题,能极大地促进你的知识理解。但是,如果你不小心,可能会落入两个效率陷阱:
Practice problems should be used to highlight areas you need to develop a better intuition for。 Then techniques like the Feynman technique, which I’ll discuss, handle that process much more efficiently。
Non-technical subjects, ones where you mostly need to understand concepts, not solve problems, can often get away with minimal practice problem work。 In these subjects, you’re better off spending more time on the third phase, developing insight。
