Frequently Asked Questions
Is GSA easy to score in CSS?
Yes — with disciplined preparation, 70+ is realistic. The science section is high-school level; the ability section is basic math.
How much math is in GSA?
About 40% of the paper. Most questions are basic arithmetic, ratio, percentage, and data interpretation — no calculus.
What’s the best book for GSA?
Caravan/Dogar GSA book for syllabus coverage, supplemented by a school general-science textbook and R.S. Aggarwal for quant practice.
