B. Sectional view of assembly of machine parts – 30 marks
Though these are the marking trends, you should devote equal time to each section.
Tips for preparation
- Practice drawing of engineering objects in 1st/3rd angle, inclusive of cross-sectional drawings, plane and elevation.
- Familiarize yourself with drawing standards, symbols and software.
- Keep visualizing things and different views for those things.
- Make flashcards to remember the definitions of the new terms you come across, and be thorough with the theoretical part.
How to score well
- Before you start the exam, utilize the first 15 minutes to scan the paper. Read the question paper thoroughly before jumping to write the answers.
- Among the questions with internal choices, select the ones that you plan to attempt, and frame skeletons of the answers you are going to write for these questions.
- Follow a pattern. For example, in case you start with long answer questions, complete that section and only then move to short or very short answer section.
- Highlight the important points and write your answer in points to enhance visibility.
