Which Biology chapters are the toughest and most boring yet high-scoring?

Many students complain that some Biology chapters, especially in Class 12, feel tough or boring, but ironically they are high-scoring. Chapters like Plant Physiology and Morphology of Flowering Plants are memorization-heavy and can feel monotonous. Yet, they repeatedly contribute questions in NEET, making them valuable. Similarly, chapters like Human Reproduction or Reproductive Health can feel lengthy but are crucial for Biology’s 50% weightage. The key is to tackle these “boring” chapters with short notes, diagrams, and regular quick revisions. What feels tedious during preparation often becomes the reason for scoring well in the exam.
