PIEAS MS Program Written Test Structure

The duration of the written test shall be 3 hours (180 minutes). The test consists of two sections:

1. General Section
2. 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
• General Mathematics – 20 questions
• English Language – 10 questions
