Biology emphasises on the underlying principles that are common to animals and plants. Students are expected to understand discoveries and innovations in biology.
But despite understanding and studying throughout the year, students often fail to score well. This is because most students lose confidence and feel nervous in the examination hall. Biology teacher Shahnawaz Ansari shares following tips to help students score well. Excerpts
Skill-wise weightage
Remembering: Knowledge-based simple questions. They include knowing specific facts, terms, concepts, principles, or theories, identify, define, or recite, information: 10%
Understanding: It means comprehension, that is, to be familiar with meaning and to understand concepts. It also means to learn to interpret, compare, contrast, explain, paraphrase information: 30%
Application: Use abstract information in concrete situation, to apply knowledge to new situations, use given content to interpret a situation, provide an example, or solve a problem: 30%
Evaluation & Analysis: Classify, compare, contrast, or differentiate between different pieces of information, organise and/or integrate unique pieces of information from a variety of sources: 17%
Creating: Appraise, judge, and/or justify the value or worth of a decision or outcome, or to predict outcomes based on values: 13%
