# Memorisation techniques [closed]

How do I memorize concepts/topics. Considering theres so many things in electronics and its difficult to understand too. Taking a test in a few days and have so much to study

• Understand the subjects, then you don't have to memorize as much. Understanding comes from using the concepts. – JRE Aug 15 '20 at 13:59
• I second @JRE’s answer. I remember freaking out about a final exam because there was too much material to review. I focused on the principles and understanding instead of memorizing. That’s the goal of the class anyway. – Joe Mac Aug 15 '20 at 14:09
• I’m voting to close this question because it is a question about learning techniques rather than electronics. – The Photon Aug 15 '20 at 14:55
• @BeatriceUK here is an illustration of the difference between memorizing and understanding ... a child came home from school excited. "daddy, daddy, we learned how to count apples today!" ... "that's wonderful dear. how many oranges are on the table?" ... "don't be silly daddy, we learned how to count apples" ... lol – jsotola Aug 15 '20 at 16:32
• @tlfong01: That wasn't posted as a cheat sheet. It is a prime example of what not to do. The whole thing is nothing but middle school algebra. If you understand what you are working with, then "P=EI", "E=IR", and some simple algebra will get you through. That's how I handled Ohm's law and the power law in school, and to this day. No level of memorisation will replace actually understanding the things you are working with. – JRE Aug 16 '20 at 15:41
