Preparation Strategy
The exam is heavy on technical subjects, with Part B commanding 120 out of 210 marks. You should allocate about 70% of your study time to these core technical concepts, especially Automobile Engineering and Internal Combustion Engines. For Part A, don’t overlook Current Affairs and the Constitution; staying updated with the news is a simple way to pick up those 30 marks. Practice with past papers to improve your pacing, as you only have 3 hours to cover 210 questions. Always keep the 0.25 negative marking in mind when guessing.
