PIEAS MS Program Written Test Structure
The duration of the written test shall be 3 hours (180 minutes). The test consists of two sections:
- General Section
- Subject-Specific Section
1. General Section
The General Section is compulsory for all candidates. It contains 50 questions with a time allocation of 90 minutes.
- Basic Physics – 20 questions
