Before answering, carefully read the question to identify the key terms and what is being asked. Structure your answer logically, directly addressing the question’s prompt. Avoid unnecessary detail; focus on providing accurate and relevant information.
For instance, a short answer question might ask to define “raster graphics” and “vector graphics,” requiring brief but accurate definitions highlighting their key differences.
Essay Questions
Essay questions require more in-depth responses, demonstrating a comprehensive understanding of the topic. These questions often involve analysis, evaluation, or comparison. Planning is key; before writing, Artikel your main points and supporting evidence. Structure your essay logically with an introduction, body paragraphs, and a conclusion. Use clear and concise language, supporting your arguments with relevant examples and evidence.
A typical essay question might ask to compare and contrast different 3D modeling techniques, requiring a structured response detailing the strengths and weaknesses of each method with supporting examples.
