Don't simply read flashcards; produce them actively.
Write questions on one side and brief answers on the other.
Utilise bullet points, diagrams, and abbreviations while making notes. These brief notes will be useful to revise large topics in a short time.
Identify important terms and concepts in your textbook or notes. Highlight different categories with different colored highlighters (e.g., dates, formulas, definitions).
Writing involves more than one sense, which makes it better for memory. Write down notes in your own words.
Develop memorable acronyms or phrases to encode lists or sequences. Example: ROY G BIV (red, orange, yellow, green, blue, indigo, violet).
Link information to known places in an imaginary "palace". Imagine going through the palace, pulling out information from each place.
Describe the idea in your own words, as if you were explaining it to someone else. Find gaps in your knowledge and go back over those areas.
