Make a proper study schedule for yourself.
Prioritise important tasks first.
Connect the new ideas with the information you already know about.
Look for patterns between the two topics.
Create a visual representation of the learning.
Use flashcards, flowcharts, and others to make studying interesting.
Make stories and rhymes from what you have studied.
Use mnemonics to recall complex information.
Use abbreviations to make the readings effective.
Properly organise the notes.
Review notes at least more than 2 times before your exams.
Read your notes aloud to retain the information for longer.
Explain your ideas to others to track your learning.
Identify your lack of information too.
Learning gets more delayed if you cram. Get adequate sleep, manage your study time, and eat healthy to stay de-stressed.
