Read one paragraph, then close the book , close your eye and try to repeat the most of what you just read, compare it with what is in the book, write it down from your memory after that.
It should work. It is my tried and tested method I used in Pakistan.
By the way why do you have to memorize anything , do you need to comprehend and understand to answer the questions in the exams ?
In Pakistan rote learning is required and needed to get good marks in exam , if you are in Europe then I do not think you will need to memorize anything.
