FIRST IAS INSTITUTE runs Prelims MCQs and Mains writing in the same weekly cycle. The published Pre+Mains (without Optional) lines are this integrated course — CSAT included, batch size 35.
The UPSC Prelims + Mains Integrated Course at FIRST IAS INSTITUTE is the published without Optional programme: GS Prelims, CSAT, Mains GS/Essay writing and weekly mocks for both stages in the same week. Classroom payable fees (2026): 1 year ₹1,47,500, 2 year ₹2,17,500, 3 year ₹2,71,500.
If you need Optional papers (500 Mains marks), use UPSC Course with Optional instead — that is integrated GS plus Optional, not a different exam.
Prelims is screening (GS-I + CSAT). Mains decides rank. Institutes that teach only MCQs until June force a writing restart in July. FIRST IAS’s published methodology runs weekly Prelims + Mains mocks together from the foundation weeks onward.
Printed chapter-wise books, newspaper classes and daily writing sit on the same calendar. Batch cap 35 so both MCQ analysis and Mains copies can be checked.
Offline without Optional: 1 year, 2 year, 3 year. Online live without Optional: batch-pm-25 / 26 / 27 under All Courses. Recorded Pre+Mains exists for jobs that cannot do live hours.
Every Fees Structure line states CSAT is included. Qualifying Paper II still fails ranks; it is not “later.” Dedicated CSAT teaching (including faculty listed for CSAT) is described on UPSC CSAT Course and CSAT preparation.
