About Objective Mechanical Engineering

Objective mechanical engineering tests are assessments designed to gauge your knowledge and understanding of core mechanical engineering principles. These exams are often used for various purposes, including:

• Screening candidates for jobs or internships: Companies might use them to evaluate the fundamental knowledge of potential mechanical engineers.
• Licensure: The Fundamentals of Engineering (FE) Exam is a crucial step towards becoming a licensed professional engineer in the US.
• Graduate school admissions: The GRE Subject Test in Mechanical Engineering helps assess an applicant’s preparedness for graduate studies in the field.

Objective Mechanical Engineering Exam formats; What to expect

• Question Types: Primarily multiple-choice (MCQs) with some variations depending on the exam:
  • True/False: Identify statements as true or false.
  • Matching: Match terms/concepts with their definitions.
  • Fill-in-the-Blank (less common): Fill in missing words/phrases.
• Timed: Work efficiently to analyze questions and select answers within the time limit.
• Focus: Understanding of core concepts over complex calculations. Some basic calculations might be involved for data interpretation or answer selection.
