1) What helped me is trying to really understand and comprehend the topic. This helped me memorize a lot easier.
2) You could also use flashcards, an app called Quizlet allows you to make flashcards and this helped me memorize things a lot too.
3) Another tip is to try to re-read information when you study. I usually try to re-read things when I am studying for an exam and I do this over and over again which has helped improve my comprehension in a topic.
Hope this helped (:
Read the whole answer only to understand .
Don't think of memorising in one go.
Break the question in parts (as many u wish)
Now go through one part and learn it loudly.
Now check whether u have learnt by hiding the answer.
If yes: repeat process 4 and 5 till u complete the answer.
If not: try to learn again and again.
Hope tgis helped
