There is an article available on the BBC’s website that explores the easy ways to learn that you can apply to your studying that do not require more effort or time than what you usually do; unless you do nothing then you will need to put in more effort to pass your exams. The article also suggests a useful app you can use.
Here is a quick summary of the techniques for you to try:
Embracing ignorance – making mistakes is a good thing because you remember your mistakes easily; just make sure you correct them!
Surfing the memory’s waves – the key is to increase the timing before re-testing yourself.
Buffet studying – spend small blocks of time on a variety of subjects and skills – rather than concentrating on a single topic.
Story telling – any form of elaboration can enhance your memory for the material such as reading it out as a story or speech.
