For biology, you can summarise the long paragraphs from biology notes into key points and remember them.
During exams, you can elaborate those points in your own words. So mugging up pages after pages can be avoided.
Also, in biology, diagrams play an important role, so practice them simultaneously; diagrams need not be artistic but specific, neat and labelled.
While writing answers, keep your sentences short to avoid mixing concepts and try and include biological terms rather than common words.
