• Instructions:  Carefully read and understand the instructions provided in the TMA. Look for details like the number of questions, expected word count, and any specific formatting guidelines.
• Evaluation Criteria:  Sometimes TMAs specify how marks are distributed. This can be for answering specific questions, including diagrams, or following formatting guidelines.

2. Research and complete the TMA:

• Gather Information:  Use your NIOS study materials, textbooks, or credible online sources to gather information relevant to the TMA topic.
• Answer the Questions:  Address each question in the TMA comprehensively. Use your research and understanding to provide clear and well-explained answers.
