GATE Mechanical Prep: PERT and CPM Solved Exam Questions

Preparing for the competitive GATE Mechanical Engineering exam requires not just knowing the formulas, but understanding how to apply them under exam conditions. This text-based guide focuses directly on the critical project management topics of PERT and CPM, helping you bridge the gap between theory and exam success. You will start with a clear, structured review of core concepts and definitions before diving into systematic, written walkthroughs of past exam questions. By reading through these detailed explanations, you will learn how to analyze network diagrams, calculate critical paths, and solve probability-based scheduling problems with speed and accuracy. What you'll learn: - Understand foundational project management terminology including activities, events, and network rules - Calculate earliest and latest start/finish times, total float, and free float for project activities - Identify the critical path and determine overall project duration using systematic algorithms - Apply PERT three-estimate methods to calculate expected activity times and standard deviations - Solve probability questions regarding project completion dates using normal distribution concepts - Analyze past exam questions from mechanical engineering papers with step-by-step written explanations The course begins with a concise refresher of essential industrial engineering formulas and network rules, followed by a curated selection of past exam problems arranged by concept complexity. Each problem is broken down with clear mathematical steps and logical reasoning to build your confidence. This course is designed for GATE Mechanical Engineering aspirants who have a basic understanding of industrial engineering and want to sharpen their problem-solving skills for the exam. No advanced prerequisites are required, as we review all fundamental formulas from scratch. Strengthen your exam preparation and master every PERT and CPM question on your test.
