Frequently Asked Questions
Is Environmental Sciences scoring?
Yes — increasingly so. Strong candidates score 70-85 by combining science, policy, and Pakistan-specific data.
Does it overlap with Geography?
Partially. Environmental Sciences is more chemistry/policy oriented; Geography is more spatial. Many candidates pair them.
Do I need a science background?
Helpful but not essential. The syllabus is interdisciplinary and accessible to social-science graduates with 3-4 months of preparation.
